Rubymine - Rails gem not found

Question

I installed Rails 3.2.3 and Ruby 1.9.3 going through this solution - http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/. It's really amazing and effortless. There were no errors while I did this.

Now I try to create a Rails project in Rubymine 4 but there's an error: "Rails version - no Rails gem found".

Terminal shows me:

alex@ubuntu:~$ rails -v
Rails 3.2.3
alex@ubuntu:~$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

Answer 1

This may help for rubymine.

You need to add ruby sdks

In RubyMine from file -> settings -> ruby Sdk and Gems -> add sdk

You can add multiple ruby version sdks and its gems

You can edit project specific ruby setup after starting project from menu

run -> edit configuration -> ruby sdk (select specific rails environment)

$ which ruby  #to get current ruby path

Answer 2

For posterity: don't select a Ruby version from the wrappers folders that are generated by rvm. Ruby thinks it's OK, but you get the Rails error.

Answer 3

When gem installed locally, just add the path to the SDK:

for example: ~/.gem/ruby/2.2.0/gems on File > Project Settings > Platform Settings > SDKs > Classpath (press + button)
