如何删除gem路径？

Question

如何删除第二条路径(/home/tom/.gem/ruby/1.8)GEM PATHS:？

这是输出$ 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:
     - http://gems.rubyforge.org/

我很感激帮助!

Answer 1

在〜/ .bashrc文件中覆盖？

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

虽然感觉有点hacky.

Answer 2

你不能!我也想这样做,并没有找到办法.然后我在RubyGems源代码(github.com)中查找并了解到它试图从etc/gemrc和获取路径~/.gemrc.如果失败(并且GEM_PATH环境变量也失败),则假定它~/.gem是默认路径.

因此,Max William是对的,你要么出口GEM_PATH要么创造一个~/.gemrc.当然,这不是一个黑客行为!:-)

希望有点清理过的东西!
