<RubyGems> How to change gem environment settings?
I installed rbenv and set up ruby and gems. Now if I run gem env then I got the following:
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
- /Users/myusername/Tools/.rbenv/shims
- /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 DIRECTORY and 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 variables without affecting normal functioning of ruby, gem and rbenv etc.?
Thanks!

Actually I searched online and found the solution.
Just put the following in your .profile (Max OS) or .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.
