How to delete a gem path?

Question

Hi there,

how can I delete the second path (/home/tom/.gem/ruby/1.8) of "GEM PATHS:" ?

Here's the output of "$ gem env":

RubyGems Environment:

• RUBYGEMS VERSION: 1.3.5
• RUBY VERSION: 1.8.7 (2009-06-12 patchlevel 174) [i486-linux]
• INSTALLATION DIRECTORY: /usr/lib/ruby/gems/1.8
• RUBY EXECUTABLE: /usr/bin/ruby1.8
• EXECUTABLE DIRECTORY: /usr/bin
• RUBYGEMS PLATFORMS:
  • ruby
  • x86-linux
• GEM PATHS:
  • /usr/lib/ruby/gems/1.8
  • /home/tom/.gem/ruby/1.8
• GEM CONFIGURATION:
  • :update_sources => true
  • :verbose => true
  • :benchmark => false
  • :backtrace => false
  • :bulk_threshold => 1000
• REMOTE SOURCES:

Thanks a lot! Tom

Answer 1

Override in your ~/.bashrc file?

#in ~/.bashrc
export GEM_PATH=/usr/lib/ruby/gems/1.8

Feels kind of hacky though.

Answer 2

I would love to know where RubyGems sticks the gem paths. I have scoured my system looking for /etc/gemrc, ~/.gemrc, etc and I cannot find ANYTHING that suggest where these paths are hard coded.

I'm on a mac and having some serious issues trying to upgrade Ruby from 1.8.6. I've tried the RVM (Ruby Version Management) and MacPorts - and I think I'm getting overlap for my gem paths.

Frankly, I don't think the ~/.gemrc or /etc/gemrc is an elegant solution. Surely there must be a file SOMEWHERE that contains this information? Cryptic. Ruby. Bullshit.
