<RubyGems> How to change gem environment settings?
提问by Bruce
I installed rbenvand set up ruby and gems. Now if I run gem envthen I got the following:
我安装rbenv并设置了 ruby 和 gems。现在，如果我运行，gem env那么我得到以下信息：
RubyGems Environment:
- RUBYGEMS VERSION: 2.2.2
- RUBY VERSION: 2.1.0 (2013-12-25 patchlevel 0) [x86_64-darwin13.0]
- INSTALLATION DIRECTORY: /Users/myusername/Tools/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0
- RUBY EXECUTABLE: /Users/myusername/Tools/.rbenv/versions/2.1.0/bin/ruby
- EXECUTABLE DIRECTORY: /Users/myusername/Tools/.rbenv/versions/2.1.0/bin
- SPEC CACHE DIRECTORY: /Users/myusername/.gem/specs
- RUBYGEMS PLATFORMS:
- ruby
- x86_64-darwin-13
- GEM PATHS:
- /Users/myusername/Tools/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0
- /Users/myusername/.gem/ruby/2.1.0
- GEM CONFIGURATION:
- :update_sources => true
- :verbose => true
- :backtrace => false
- :bulk_threshold => 1000
- REMOTE SOURCES:
- https://rubygems.org/
- SHELL PATH:
- /Users/myusername/Tools/.rbenv/versions/2.1.0/bin
- /Users/myusername/Tools/.rbenv/libexec
- /Users/myusername/Tools/.rbenv/plugins/ruby-build/bin
- /opt/local/bin
- /opt/local/sbin

- /usr/bin
- /bin
- /usr/sbin
- /sbin
- /usr/local/bin
- /Users/myusername/Tools/./bin
- /Users/myusername/Tools/.rbenv/bin
Well.. all looks good except for SPEC CACHE DIRECTORYand GEM PATHS, all others have self-configured paths. (So I really don't want any dev-related directories directly placed in my user home folder.) Is there a way to flexibly change these two env variableswithout affecting normal functioning of ruby, gemand rbenvetc.?
嗯.. 除了SPEC CACHE DIRECTORYand之外，所有看起来都不错GEM PATHS，所有其他人都有自己配置的路径。（所以，我真的不希望任何开发相关的目录直接放置在我的用户的个人文件夹。）有没有办法来灵活地更改这两个env variables在不影响正常运作ruby，gem并rbenv等？
Thanks!
谢谢！

Actually I searched online and found the solution.
实际上我在网上搜索并找到了解决方案。
Just put the following in your .profile (Max OS) or .bashrc (Linux)
只需将以下内容放入您的 .profile (Max OS) 或 .bashrc (Linux)
export GEM_PATH=/Users/myusername/Tools/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0
export GEM_SPEC_CACHE=/Users/myusername/Tools/.rbenv/versions/2.1.0/lib/ruby/gems/specs
Make sure the folder you put there existed. Then source the .profile or .bashrc, or simply restart your terminal. It is tested working now my env is correct.
确保您放置在那里的文件夹存在。然后获取 .profile 或 .bashrc，或者简单地重新启动终端。现在我的环境是正确的，它已经过测试。
