How to change gem environment settings?

Question

I installed rbenv and set up ruby and gems. Now if I run gem env then I got the following:

RubyGems Environment:
  - RUBYGEMS VERSI         


        

Answer 1

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.
