I've been getting this error after installing rvm and rails with rvm. Can anyone help me out?

/Library/Ruby/Site/1.8/rubygems.rb:779:in report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError) from /Library/Ruby/Site/1.8/rubygems.rb:214:in activate' from /Library/Ruby/Site/1.8/rubygems.rb:1082:in `gem' from /usr/bin/rails:18

Thanks!

try 'rvm list' and then 'rvm use <the rvm you installed rails on>' you need to load the environment rails live in first. - sled
I did that and now I get this error: Could not find RubyGem rails (>= 0) (Gem::LoadError) from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems.rb:244:in activate_dep' from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems.rb:236:in activate' from /usr/local/lib/ruby/site_ruby/1.9.1/rubygems.rb:1307:in gem' from /usr/local/bin/rails:18:in <main>' --> it seems like it cant even find rails? I'm so confused T_T - readmymsg123
ok try: 'rvm gem list' does rails show up there? - sled

Couple of things to look at:

  • Make sure Rails is indeed installed. I'm bringing up this point because you mentioned that you installed Rails with RVM, which is inaccurate. You install Rubies with RVM but you install Rails with Bundler (you can see Bundler as an RVM for gems rather than rubies). So ensure that you have a line that says gem 'rails' in your Gemfile and then run bundle install.

  • As pointed out by other answers, make sure you are using the right ruby and gemset (where you installed the Rails gem). To do so run rvm use <your_ruby>@<your_gemset>.

Are you sure you're actually in the RVM Ruby right now? I often hit this error when I forget to enter rvm use MY_RUBY_VERSION. It's looking for the rails gem, but can't find it.
