Jenkins Slave Doesn't Use Same Ruby Version As On Local Terminal

问题

I am using a OSX Jenkins slave to run some build commands for Xcode. When I run gem environment in my local terminal, this is what I get.

RubyGems Environment:
  - RUBYGEMS VERSION: 2.4.8
  - RUBY VERSION: 2.2.0 (2014-12-25 patchlevel 0) [x86_64-darwin15]
  - INSTALLATION DIRECTORY: /Users/nvitas/.rvm/gems/ruby-2.2.0
  - RUBY EXECUTABLE: /Users/nvitas/.rvm/rubies/ruby-2.2.0/bin/ruby
  - EXECUTABLE DIRECTORY: /Users/nvitas/.rvm/gems/ruby-2.2.0/bin
  - SPEC CACHE DIRECTORY: /Users/nvitas/.gem/specs
  - SYSTEM CONFIGURATION DIRECTORY: /Users/nvitas/.rvm/rubies/ruby-2.2.0/etc
  - RUBYGEMS PLATFORMS:
    - ruby
    - x86_64-darwin-15
  - GEM PATHS:
     - /Users/nvitas/.rvm/gems/ruby-2.2.0
     - /Users/nvitas/.rvm/gems/ruby-2.2.0@global
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :backtrace => false
     - :bulk_threshold => 1000
  - REMOTE SOURCES:
     - https://rubygems.org/
  - SHELL PATH:
     - /Users/nvitas/.rvm/gems/ruby-2.2.0/bin
     - /Users/nvitas/.rvm/gems/ruby-2.2.0@global/bin
     - /Users/nvitas/.rvm/rubies/ruby-2.2.0/bin
     - /Users/nvitas/.rvm/bin
     - /usr/local/opt/ruby/bin
     - /usr/local/bin
     - /usr/bin
     - /bin
     - /usr/sbin
     - /sbin

This is what I expect. Now when I run the exact same command through Jenkins, I get this

RubyGems Environment:
  - RUBYGEMS VERSION: 2.0.14
  - RUBY VERSION: 2.0.0 (2015-04-13 patchlevel 645) [universal.x86_64-darwin15]
  - INSTALLATION DIRECTORY: /Users/nvitas/.rvm/gems/ruby-1.9.2-p320
  - RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby
  - EXECUTABLE DIRECTORY: /Users/nvitas/.rvm/gems/ruby-1.9.2-p320/bin
  - RUBYGEMS PLATFORMS:
    - ruby
    - universal-darwin-15
  - GEM PATHS:
     - /Users/nvitas/.rvm/gems/ruby-1.9.2-p320
     - /Users/nvitas/.rvm/gems/ruby-1.9.2-p320@global
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :backtrace => false
     - :bulk_threshold => 1000
  - REMOTE SOURCES:
     - https://rubygems.org/

I'm running everything in the same directory, the same user, nothing is different, so why is the ruby version and directories wrong? The only config setting in my Jenkins Slave is the PATH variable which has the value

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/nvitas/.rvm/gems/ruby-2.2.0/bin:/Users/nvitas/.rvm/bin:/Users/nvitas/.rvm/gems/ruby-2.2.0

Other than that everything is what comes installed.
