无法启动Rails控制台

Question

Rails console doesn't work on my production server. Here is what happens:

root@myapp:/webapps/myapp/current# rails c
/usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- rails/cli (LoadError)
    from /usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from /usr/local/rvm/gems/ruby-1.9.2-p180@rails/gems/rails-3.0.5/bin/rails:8:in `rescue in <main>'
    from /usr/local/rvm/gems/ruby-1.9.2-p180@rails/gems/rails-3.0.5/bin/rails:3:in `<main>'

Previously I was getting Readline related error, explained here: Problems with the rails console, RVM and readline

I tried the propsoed fix, and now I'm not getting readline error. Still the console won't launch.

Here is the rvm info output:

ruby-1.9.3-p194:

Locally I was always able to launch rails console, but on the remote machine something is different.

upd: My best guess so far is that Rails is missing correct path to "rails/cli". Have to research and see how this can be fixed.

Answer 1

Try again with a normal user, after installing RVM as a normal user.
Installing RVM as root is a pain as far as I experienced, I particularly had paths issues.

Answer 2

If that won't work you can always switch to rbenv. It is lighter and have everything you need on a localhost
