Setup Ruby On Rails on Ubuntu 15.10 Wily Werewolf

Thanks for this amazing tutorial! you just described every step!

Thanks! It's helpful to me.

Likely that if you are using Ruby version 2.2.3 with RVM is bound to have problems when installing libraries that require installing native extensions. For some reason (IDK if because the RVM's ruby binary is not correctly compiled), when installing ruby 2.2.3 you'll run into that kind of problems.

The solution I found was installing from source (i.e you compile and install ruby locally on your machine).
To accomplish this do the following:

1. Install Ruby 2.2.3 normally with RVM ("rvm install 2.2.3; rvm use 2.2.3")
2. Once installed issue the command "rvm reinstall 2.2.3 --disable-binary"

Another solution is to fallback to a previous version such as 2.2.2 or 2.2.1

This may be helpful if you run into this problem.

Cheers!

For those who have trouble installing PostgreSQL part on Kubuntu 15.10 :

// remove all installation of postgre first
$ sudo apt-get purge postgresql*

// try changing <precise-pgdg> into <wily-pgdg> on apt sources
$ sudo sh -c "echo 'deb http://apt.postgresql.org/p... wily-pgdg main' > /etc/apt/sources.list.d/pgdg.list"

// install latest version of PostgreSQL (9.4 as it written)
$ sudo apt-get install postgresql libpq-dev

When I do rbenv install 2.2.3 command I get the error: zsh: command not found: rbenv, I am doing the 15.10 install

I should talk to Ruby On Rails community and include your rails installation guides on the official website.

Awesome easy to follow guide! Enabled me to put Ruby on my server without issue!

Now What ?

I get this error when i try to create the PostgreSQL user:

createuser: could not connect to database postgres: 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"?

--- EDIT ---

I used "/etc/init.d/postgresql start", then worked.

Thank you very much.

When I goto localhost:3000 I get this error:

raise Gem::LoadError, "Specified '#{spec[:adapter]}' for database adapter, but the gem is not loaded. Add `gem '#{e.name}'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord)."

Not sure what needs to be done.

Sir why you recommended rbenv?

I did all the steps above successfully. However, when launching http://localhost:3000 I get the following error:

Unable to connect
Firefox can't establish a connection to the server at localhost:3000.

Please let me know how to fix it.

Getting error while installing rails as follows:-
