I got as far as:

gem install rails -v 4.2.0

Then it failed:

ERROR: Error installing rails:

-----
The file "/usr/include/iconv.h" is missing in your build environment,
which means you haven't installed Xcode Command Line Tools properly.

To install Command Line Tools, try running `xcode-select --install` on
terminal and follow the instructions. If it fails, open Xcode.app,
select from the menu "Xcode" - "Open Developer Tool" - "More Developer
Tools" to open the developer site, download the installer for your OS
version and run it.

Tried both these methods and when I ran the command-line install method I get this:

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

Is this article up to date? There is a Ruby on Rails version 4.2.1 now. Also I'm using OS X 10.10.2 and XCode 6.2. Should I even be following this? Thanks.

Very Good! Thanks

Hi,
Could anyone help me out?

I'm getting the following error while installing Rails.

Can anybody help me out, please? I'm new to this.

It sounds like you aren't using the proper version of Ruby and it's trying to install in your system Ruby. Make sure you didn't miss any commands and try restarting your terminal. When you run "which ruby" you should get something like "/Users/chris/.rbenv/shims/ruby".

Everything works great until I get to the rails portion where I get 'extconf failed, exit code 1'

Any advice? Everything I searched for hasn't helped yet.

Is it normal to have Ruby version different to RubyGems version? Here's a screenshot of what I'm talking about:

Reply

Yes, Ruby and Rubygems get updated at different times. Everything looks good there but you should upgrade to Rails 4.2.1! :)

Hi, i truly enjoyed the post. Very helpful. Now I have with the installation i get this error

Access denied for user 'root'@'localhost' (using password: YES) . I have a question can a previous installation of MySQL server and Apache server cause conflict with the installation with Ruby on Rails? If not how to solve this problem.

Reply

Hey Sarah, if you haven't fixed this yet, the error basically says that your database password doesn't match what was set up with MySQL. If you used homebrew to install it, then the username is usually the same as the user you login as and the password is empty.

I'm having a problem in installing ruby:

1) First I did $ rbenv install 2.2.2, it gave error.

2) Then I did $ sudo rbenv install 2.2.2, it returned:
Installed ruby-2.2.2 to /Users/mavericks/.rbenv/versions/2.2.2

3) Then I did the other one, $ rbenv global 2.2.2, returned “permission denied”. So I did with sudo and it returned no errors.

But now when I do $ ruby -v it returns ruby 1.9.3p547 (2014-05-14 revision 45962) [x86_64-darwin13.2.0]

And when I do $ rbenv versions it returns:
system
* 2.2.2 (set by /System/Library/Frameworks/Ruby.framework/Versions/.ruby-version)

So, it seems that I have 2.2.2 installed but I doesn't run it when I try to through rbenv.
Anybody can help me?

I get this error message during the rails installation step, after pasting the command "gem install rails -v 4.2.1" in terminal:

Error installing rails:

invalid gem: package is corrupt, exception while verifying: undefined method `size' for nil:NilClass (NoMethodError) in /Users/avinash/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/cache/activesupport-4.2.1.gem

Help appreciated.

Edit - After a little perseverance all is now working as you have explained, amazing how one little deviation from the original instructions can cause issues, thanks for the guide Chris!

Actually I had Git configured before following these steps itself. So, just to test the working, i tried,

ssh -T git@github.com

But, the output was, "Permission denied (publickey)"

So, tried configured again exactly as per the steps above and the result didn't change.
But, I have been using GitHub without any problem before on my mac.
Does this output affect my use of Ruby on Rails?
Please help. :)
Thanks In Advance.

Help!? don't know how to fix this, I run this command:
gem install rails -v 4.2.1

Hey everyone,

Bit of help needed:

ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory

How do i fix?

Looks like you may not be using the Ruby (and the gem command) from the rbenv install. Try restarting your terminal and making sure you get something like "/Users/chris/.rbenv/shims/ruby" from running "which ruby"
