Question

When I tries to install rails:

root@li44-48:/# gem install rails
Successfully installed rails-3.2.1
1 gem installed
Installing ri documentation for rails-3.2.1...
Installing RDoc documentation for rails-3.2.1...

But when I do:

root@li44-48:/# rails
-bash: rails: command not found

I checked gem env and it displays:

RubyGems Environment:
  - RUBYGEMS VERSION: 1.8.15
  - RUBY VERSION: 1.9.3 (2011-10-30 patchlevel 0) [i686-linux]
  - INSTALLATION DIRECTORY: /usr/lib/ruby/gems/1.9.1
  - RUBY EXECUTABLE: /usr/bin/ruby

     - :benchmark => false
     - :backtrace => false
     - :bulk_threshold => 1000
  - REMOTE SOURCES:
     - http://rubygems.org/

Also the folder root@li44-48:/usr/lib/ruby/gems/1.9.1/gems/rails-3.2.1# is empty.

Any ideas on how to fix this?

Answer 1

In an effort of rage quit, I:

1. removed ruby
2. removed gem

and recompiled both from source, and now gem install rails is fully working again.
