Setup Ruby On Rails on
Windows 10

A guide to setting up a Ruby on Rails development environment



This guide is a work in progress as the new Bash on Ubuntu on Windows Linux Subsystem is in beta. There is a lot of functionality not implemented yet so you'll find that, while the basics might work, some of the more advanced and complex things won't.

This will take about 45 minutes.

We will be setting up a Ruby on Rails development environment on Windows 10.

The reason we're going to be using Bash on Ubuntu on Windows because it allows you to run Linux on your Windows machine. Most Ruby on Rails tutorials and dependencies work best on Linux, so this allows you to get the best of both worlds. A Windows machine for your day to day work, and a Linux subsystem for Ruby on Rails development.

This only works on 64-bit installations of Windows. This is also in beta, so this won't be nearly as robust as running a Linux virtual machine, but it can definitely do the basics well enough.

Bash on Ubuntu on Windows is the name for the Linux Subsystem that's in beta right now for Windows. It allows you to run Linux on Windows without having to run a VM.

Right now, this update is only available to those on the "Fast" option in the Windows Insider program. You'll want to join the Windows Insider program and set your Insider level to "Fast".

Here's how you can join the Windows Insider program.

The first step is to enable "Developer mode" in Windows. You can do this by opening up Settings and navigating to to Update & Security, then "For Developers". Click the "Developer mode" option to enable it.

Developer mode

Now we need to enable to Windows Subsystem for Linux. You can do this by opening Control Panel, going to Programs, and then clicking "Turn Windows Features On or Off". Looking for the "Windows Subsystem for Linux" option and check the box next to it.

Subsystem for linux

The earliest working version of this for me is Windows 10 release 14352. If Windows Subsystem for Linux doesn't show up in the list right away, you may need to make sure you're part of the Windows Insider program and set to the "Fast" level, update Windows, reboot, or wait a few days for the option to become enabled. I enabled Developer mode and had to wait two days or so before the option became available. I'm not sure how this feature propogates, but try a couple of these options and you should get it.

Once you've got this installed and after rebooting, we can start setting up Bash on Ubuntu on Windows.

Start by searching for "bash" in the start menu.

Bash

Next we'll follow the installation steps to get Bash on Ubuntu on Windows installed.

Installing bash

Once that's complete, you can open up the Start menu again and search for "Bash". This time it will have the Ubuntu logo.

Bash on ubuntu on windows

Now you've got a functional Ubuntu Linux installation running on your Windows machine!

Hello linux

From here we can follow the normal Ubuntu setup steps to install Ruby, Rails, and our database.

Choose the version of Ruby you want to install:

The first step is to install some dependencies for Ruby.

sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev

Next we're going to be installing Ruby using one of three methods. Each have their own benefits, most people prefer using rbenv these days, but if you're familiar with rvm you can follow those steps as well. I've included instructions for installing from source as well, but in general, you'll want to choose either rbenv or rvm.

Choose one method. Some of these conflict with each other, so choose the one that sounds the most interesting to you, or go with my suggestion, rbenv.

Installing with rbenv is a simple two step process. First you install rbenv, and then ruby-build:

cd
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

rbenv install 2.5.0
rbenv global 2.5.0
ruby -v

The installation for rvm is pretty simple:

sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
curl -sSL https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
rvm install 2.5.0
rvm use 2.5.0 --default
ruby -v

Arguably the least useful Ruby setup for development is installing from source, but I thought I'd give you the steps anyways:

cd
wget http://ftp.ruby-lang.org/pub/ruby/2.5/ruby-2.5.0.tar.gz
tar -xzvf ruby-2.5.0.tar.gz
cd ruby-2.5.0/
./configure
make
sudo make install
ruby -v

The last step is to install Bundler

gem install bundler

rbenv users need to run rbenv rehash after installing bundler.

We'll be using Git for our version control system so we're going to set it up to match our Github account. If you don't already have a Github account, make sure to register. It will come in handy for the future.

Replace my name and email address in the following steps with the ones you used for your Github account.

git config --global color.ui true
git config --global user.name "YOUR NAME"
git config --global user.email "[email protected]"
ssh-keygen -t rsa -b 4096 -C "[email protected]"

The next step is to take the newly generated SSH key and add it to your Github account. You want to copy and paste the output of the following command and paste it here.

cat ~/.ssh/id_rsa.pub

Once you've done this, you can check and see if it worked:

ssh -T [email protected]

You should get a message like this:

Hi excid3! You've successfully authenticated, but GitHub does not provide shell access.

Choose the version of Rails you want to install:

Since Rails ships with so many dependencies these days, we're going to need to install a Javascript runtime like NodeJS. This lets you use Coffeescript and the Asset Pipeline in Rails which combines and minifies your javascript to provide a faster production environment.

To install NodeJS, we're going to add it using the official repository:

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs

And now, without further adieu:

gem install rails -v 5.1.4

If you're using rbenv, you'll need to run the following command to make the rails executable available:

rbenv rehash

Now that you've installed Rails, you can run the rails -v command to make sure you have everything installed correctly:

rails -v
# Rails 5.1.4

If you get a different result for some reason, it means your environment may not be setup properly.

Rails ships with sqlite3 as the default database. Chances are you won't want to use it because it's stored as a simple file on disk. You'll probably want something more robust like MySQL or PostgreSQL.

There is a lot of documentation on both, so you can just pick one that seems like you'll be more comfortable with. If you're coming from PHP, you may already be familiar with MySQL. If you're new to databases, I'd suggest skipping to setting up PostgreSQL.

You can install MySQL server and client from the packages in the Ubuntu repository. As part of the installation process, you'll set the password for the root user. This information will go into your Rails app's database.yml file in the future.

sudo apt-get install mysql-server mysql-client libmysqlclient-dev

Installing the libmysqlclient-dev gives you the necessary files to compile the mysql2 gem which is what Rails will use to connect to MySQL when you setup your Rails app.

When you're finished, you can skip to the Final Steps.

The easiest way to setup PostgreSQL is to install it on Windows using one of the Windows installers. You'll be able to run it in Windows and connect to it through Linux.

Download PostgreSQL for Windows and install it.

Pay attention to the username and password you setup during installation of Postgres as you will use this to configure your Rails applications later to login to Postgres when your Rails app runs.

The best place to develop Rails apps on the Windows Subsystem for Linux is to navigate to `/mnt/c`. This is actually the C: drive on Windows and it lets you use Sublime, Atom, VS Code, etc on Windows to edit your Rails application.

When you create a new Rails app, you might run into the following error: parent directory is world writable but not sticky.

If you run into this issue, you can run chmod +t -R ~/.bundle and that should fix the permissions errors and let you finish the bundle install for your Rails app.

And now for the moment of truth. Let's create your first Rails application:

# Navigate to the C: drive on Windows. Do this every time you open the Linux console.
cd /mnt/c

# Create a code directory at C:\code for your Rails apps to live (You only need to do this once)
mkdir -p code

#### If you want to use Postgres
# Note that this will expect a postgres user with the same username
# as your app, you may need to edit config/database.yml to match the
# user you created earlier
rails new myapp -d postgresql

#### or if you want to use SQLite (not recommended)
# rails new myapp

#### Or if you want to use MySQL
# rails new myapp -d mysql

# Then, move into the application directory
cd myapp

# If you setup MySQL or Postgres with a username/password, modify the
# config/database.yml file to contain the username/password that you specified

# Create the database
rake db:create

rails server

You can now visit http://localhost:3000 to view your new website!

Now that you've got your machine setup, it's time to start building some Rails applications!

If you received an error that said Access denied for user 'root'@'localhost' (using password: NO) then you need to update your config/database.yml file to match the database username and password.

To edit your code in Windows: open up Sublime, Atom, VS Code, or whatever editor your prefer and point them to your folders in C:\code and you'll be able to safely edit your Rails apps in Windows and run them in Linux!

That's it! Let us know in the comments below if you run into any issues or have any other protips to share!.

Hi,

I got all the way through this so thanks for the walk through! I run "rails server -b 0.0.0.0" and the server boots fine but when I go to localhost:3000 in the browser, the browser icon spins but the server does not respond. Has anyone seen this before?

I've worked it out now. It seems that thin was the problem. I switched to webrick and the app now runs perfectly. I don't exactly no what the problem was with thin but this solution works for now!

This is great tut- based on it I installed rails 5 and ruby 2.3.1. created new test app and after rails -s I have something like this: => Booting Puma
=> Rails 5.0.0 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options

According to this site[1] you can omment out "config.file_watcher = ActiveSupport::EventedFileUpdateChecker" in this file, config/environments/development.rb

The main issue here is that inotify has been completely broken in WSL. So even if you disable listeners, tools like Guard won't work. Insiders are soon getting a partial fix, whereby files changed within WSL itself can be watched without errors.

Here's the test. First install inotify-tools, which give you some command line programs to monitor files:

$ sudo apt-get install inotify-tools

Then attempt to watch any file from the command line:

$ touch testfile.txt && inotifywatch testfile.txt
Establishing watches...
Failed to watch ./testfile.txt: Invalid argument

Note that's the same error that rb-inotify reports above.

How were you able to get the terminal to let you copy the SSH key so that you could paste it into GitHub? Copy and paste is not working for me using shortcuts or the mouse, and there is no menu that I can see.

I would just suggest taking a look at http://cmder.net/ -- This tool is a terminal lifesaver for me on Windows. It is highly configurable. By default, it adds git and some linux tools to cmd, the default shell it uses, but also allows you to use any shell (MING64, Git Bash, PowerShell, the new Bash/Ubuntu for Windows).

Today I tried getting on with the default Bash for Windows which uses the older cmd terminal, but I went bananas. Cmder gives you the text tools you need!

After I close the terminal I lost all the settings that I had installed following this tutorial. I will try install it again but I fear that the same happen again. What should I do to prevent it?

In fact, some commands stoped working since I closed the bash: rails new, rake test, bundle etc.

You probably need to reselect the ruby with rbenv or rvm.

I'm able to go through this whole tutorial for Windows 10 bash and get everything listed here working (using rvm currently). I get through all the final steps without error, got a working server, etc...

But I'm trying to follow a basic "hello world" tutorial ( found here: http://iridakos.com/2013/11... ) and when I try "rails generate controller pages" I get: "Error: Command 'rails' not recognized" as well as an info section on "Usage: spring COMMAND [ARGS]" and "Usage: rails COMMAND [ARGS]"

I'm confused as to how it could possibly say 'rails' is not recognized. I can do "rails -v", I can do "rails new", I can do "rails server", etc...

Anyone have any advice? I've tried this like 6 times now (resetting my entire linux subsystem after each failed try) using both rvm and rbenv and I end up stuck at this point every time. Any pointers as to where I'm going wrong would be greatly appreciated...thanks!

Not entirely sure on that one. Have you guys tried using rbenv instead?

For me, that was with several attempts on different machines using my preferred rbenv -- I'm going to try RVM and report back.

Gravatar
Chris Oliver (159,850 XP) on

Curious to hear what you find out. I didn't have any issues personally, but only tested rbenv. Now my Windows 10 install is borked and I haven't had time to fix it so it boots again.

Gravatar
timtilberg on

Well, I've tossed and reinstalled WSL from scratch, and tried the RVM install instead. I found that I needed to do `bash --login` to reference my profile (and load rvm) if I left the terminal -- so it might be a good idea to reference that -- apparently the default session is not interactive.

Anyway -- I did not encounter the sticky directory issues while using RVM, but I am still having the same issue as above running generators. I've tried both `rails g scaffold hotdogs good tasty` and `bundle exec rails g scaffold hotdogs good tasty` to no avail.

I just wanted to add that using the RVM install, knowing to use `bash --login` when I hop in, and ignoring the usage of any commands that utilize spring (generators, console, rake test :( ), seems to be working relatively fluidly (including the majority of rake tasks).

Obviously those are some big issues, but at least I can clone my working project down and run it currently. My last few attempts with RailsInstaller have been horribly unproductive.

Makes sense with the login shell. I wonder why they changed that, because I don't think that was how it used to be. Going to frustrate a lot of people if they keep that as the default.

This guy has a solution https://github.com/Microsof...

I've successfully tested it using WSL/Bash on Win10, with the instructions posted above using the RVM install, after running `bash --login` to ensure interactive shell.

Seems they've been making some changes to it, one of those being it's not a login shell, so you'll have to do "bash --login" for now. Still other outstanding issues. Maybe they'll get some of them fixed soon.

I had the same problem and followed the fix above. The "rails generate controller welcome homepage" finally worked only to create the "app/controllers/welcome_controller.rb" and the route "get 'welcome/homepage'. Then produces the following error "/home/Username/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/thor-0.19.1/lib/thor/actions/inject_into_file.rb:98:in `binread': Input/output error @ rb_sysopen - /home/Username/MyProject/config/routes.rb (Errno::EIO)" and following several .rbenv file names with error lines. Any ideas?

Gravatar
timtilberg on

I saw your post on SO http://stackoverflow.com/qu... but don't have enough rep to comment there, so I'll comment here.

You mention not seeing routes.rb in bash, but seeing the file in Windows, and then proceeding to copy stuff around.

The file path you mention your project to be in is a straight up linux folder (/home/User1/stuff) as opposed to a shared, mounted directory in the Windows system. With this said, I've read that interacting with files on that side (burried in appdata or wherever) of the system from Windows causes problems because of the differences in how files are handled between the systems. So, as you mention in SO, trying to copy those files from Windows will likely lead to difficulties.

I've had success with my projects living in the Windows mount area -- for example:

```
cd /mnt/C/Users/Tim/Desktop
rails new hello_world
etc
```

With the files living there, it is easy to manipulate with Windows or Linux then without causing corruption (the worst of it seems to be line ending issues, which any proper text editor can deal with).

In addition, I was using rvm, instead of rbenv.

Without knowing too much more, I'd give generic recommendations akin to "reboot it and see what happens":

- run rbenv rehash
- run bundle install
- run chmod +t -R ~/.bundle
- consider running chown -R user:user /home/user
- cd /mnt/c/Users/User/Desktop && rails new hotdogs && cd hotdogs --- and try creating a controller from there -- pay attention to what happens to the actual output

Hope you find something -- I went through a bit of hell when I tried updating ruby recently, before WSL. I had a perfectly running Ruby 2.2.0 on my system with Rails -- tried upgrading, and went through 3 weeks of frustration in trying to get a working ruby again. The method I posted above has been working really great for me finally, but I don't dare mess with it again -- it's so damned fragile!

Gravatar
Kirkos Gent (30 XP) on

Thank very much you for the recommendations. I created a new bash user to install rvm there and follow your recommendations (do you think is OK or I should reinstall the whole subsystem and use rvm this time?). I'll let you know whether it is worked for me too.

Gravatar
Kirkos Gent (30 XP) on

Well, finally, the RVM installation with the fix above works fine, like you said! (I found no way to make rbenv installation operational). Thanks a lot!

timtilberg on

Hey @excid3:disqus -- You might want to consider noting some of this stuff in the Windows specific guide, unless you are in fact seeing people successfully using rbenv. Right now the guide says rbenv is the recommended way, but I haven't been able to get it to work on WSL without issues. If you know how, that information would also be appreciated :)

Excellent!! Thanks so much for this. Up and running without a hitch after first updating to Windows 10 Anniversary. You don't need to be an Insider to update now.

I hope WSL is the real deal...I've had several fits and starts trying to get going with rails on a windows machine.

Suggestion for newbies: rather than create myapp in your linux directory, switch to your windows directory, then create myapp there.

At that point you'll have ready access to work on the myapp files via your IDE

Thus, for final step, type this at the prompt $: cd /mnt/c/Users/you

Then in this director type $: rails new myapp

Thank you! I would suggest to add to postgresql installation quide, that it is possible to make it running by installing postgres directly on windows (https://www.postgresql.org/... - prefferably version 9.3.

Unfortunately as of now, when running "sudo -u" there is a bug in the Windows Bash which states: `sudo: setresuid() [1000, 1000, 1000] -> [-1, 0, -1]: Operation not permitted`

Official bug here: https://github.com/Microsof...
Of course you can work around that by using `sudo su USER`.

Otherwise a really nice tutorial with good hints (especially the `chmod +t -R ~/.bundle` one)! Million thanks!

It's likely that everything is installed but your terminal didn't automatically load rbenv again. Double check and make sure that you followed all the rbenv lines correctly to echo the lines into your .bashrc file.

Gravatar
Alexandros Bulko on

So, today I found something better.... Open up the launcher of the bash and go to the properties.... change the target to "C:\Windows\System32\bash.exe ~ -c "/bin/bash --login"... after this you do not have to use the solution from previous comment every time you launch it.... This works automatically... It's based on the fact that normally you launch a non-login session, however, with these settings you, on the other hand, run a login session..... If you want to know more, read these threads http://askubuntu.com/questi... and https://github.com/Microsof...

Hopefully that default changes in Windows as that's unexpected behavior from anyone who is used to opening bash with a login shell automatically on any Linux install.

Incase you're not able to do rake db:migrate with pgsql try this .

I installed pgsql on local windows and not on ubuntu bash
Then did the following:
Go to you config/environments/development.rb and comment out The Line config.file_watcher = ActiveSupport::EventedFileUpdateChecker,
After this run - rails s or rake db:migrate.

This worked for me and is pretty fast too.
Earlier I was using Vagrant (VM) and this (Ubuntu on bash) is faster than vagrant method,
Just my opinion, Hope it helps :)

Hello,

Thanks for the tutorial. It really helped me to get my basic setup up and running.
Thou I did have to fiddle around to get a few things working.
I should note that 5/14/17 I was not able to do

sudo -u postgres createuser YOURUSER -s

instead I had to use

sudo sudo -iu postgres createuser YOURUSER -s

due to -u not working at the time on WSL. Also I had to start the postgresql service before creating the user with

sudo service postgresql start

Hope this comments help people trying to install it later.

Thanks again for all your help and to all the RoR community, I just spent the last few days until I had my successful attempt at installing everything I wanted on WSL (yeah there were 4, I am now familiar with lxrun.exe /uninstall /full and lxrun.exe /install to reset the entire linux subsystem :P).

PS:
I would like to see added to the tutorial some information on installing MongoDB. For the moment I will just leave the link to the official tutorial https://docs.mongodb.com/ma... small comment though there are problems starting mongodb as a service so for now the only way I have found is to use sudo mongod. Also, remember to run mkdir /data/db before starting the database (that last bit is required but it is not included in the official tutorial from mongo).

I just want to share how I was able to install postgresql 9.5.
First, after running "sudo apt-get install postgresql-common postgresql libpq-dev" I got the error:

"http://archive.ubuntu.com/u... xenial-updates/main amd64 postgresql-client-9.5 amd64 9.5.7-0ubuntu0.16.04 Hash Sum mismatch"

So, as the console sugested, I executed it again adding "--fix-missing" and it worked.

Next, running "sudo sudo -u postgres createuser username -s" throwed the error:

"psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?"

which I solved by running "sudo pg_ctlcluster 9.5 main start".

Finally, trying to run "rails db:create" I got the error:

"new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII)"

The solution for this was running:
- sudo sudo -u postgres psql
- UPDATE pg_database SET datistemplate = FALSE WHERE datname = 'template1';
- DROP DATABASE template1;
- CREATE DATABASE template1 WITH TEMPLATE = template0 ENCODING = 'UNICODE';
- UPDATE pg_database SET datistemplate = TRUE WHERE datname = 'template1';
- \c template1
- VACUUM FREEZE;

I found all the above solutions searching in Google, but I don't remember the links.

Hope it helps someone and saves them some time.

I have mysql installed on windows. Do I need to install it separately on Linux Subsystem?

How old is this guide? I ask because, as of 6/22/2017 msdn quotes:
"Languages: Javascript/node.js, Ruby, Python, C/C++, C# & F#, Rust, Go, etc.
Services: sshd, MySQL, Apache, lighttpd,"

Suggesting that ruby should have full support now?

Thanks for the tutorial!

Just a note, it's "without further ado", not "without further adieu" 😉

Great post. The install went fine, including the MySQL server installation, but when I try to connect to the MySQL server, I get the message: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

I uninstalled it (sudo apt-get remove mysql-server) and re-installed. Same error message

If I try to re-install, I get the message that the MySQL server is already installed and is the latest version. Any ideas?

The install process, despite having asked me for the root password, etc., did not automatically start the MySQL server, so the solution is simple: sudo service mysql start

I get following error. I followed everything as mentioned in the article.
Looks like mysql db is not created.
Missed any step?

Not sure if you ever got it working, and I don't have a solution really, but here are some thing's I would check.

Make sure the MySQL server is actually running. If so:

Get a visual MySQL Editor, there's alot of them, make sure your database encoding is UTF8, if it's not change it. The Visual Editor just makes it easier to check thing's out. It's a bit more simple than throwing commands into a console.

Check your Firewall, and make sure it's allowing connections on the MySQL servers port/s.

Make sure you have the correct permissions/privileges, both file system permissions, and privileges to access the MySQL service. For example MySQL may have been installed with only root, or admin access allowed. try opening the bash terminal as administrator, if that doesn't work try using sudo prefixed before commands (with, and then without admin privileges on the bash process.)

Sorry I couldn't give you a concrete solution, hope you get it working.

Good post.

I also needed to run the following, prior to installing ruby:
sudo apt-get install -y gcc libssl-dev libreadline-dev zlib1g-dev make

I installed ruby and rails correctly, but when I run my new rails app, my browser cannot connect. I must have missed something obvious somewhere. Has anyone else had this problem?

Nothing wrong! Just had to start the MySQL service: "sudo service mysql start"

Is there anything wrong with just running `sudo apt install rbenv` instead of the shell script? I was having issues with the script. Only the plugins folder was cloned...
