irb loading wrong ruby and gem path, using rbenv

I started using rbenv for ruby version management and I'm finding that irb not loading the correct ruby version and gem version. Here are the details.

irb Gem.path says:

`>> Gem.path  
 => ["/Users/Air/.gem/ruby/1.8", "/Library/Ruby/Gems/1.8", "/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8"]`

Now in irb if I type: puts $:

`>> puts $:  
/Library/Ruby/Site/1.8  
/Library/Ruby/Site/1.8/powerpc-darwin11.0  
/Library/Ruby/Site/1.8/universal-darwin11.0  
/Library/Ruby/Site  
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/vendor_ruby/1.8 /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/vendor_ruby/1.8/universal-darwin11.0  
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/vendor_ruby  
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8  
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/powerpc-darwin11.0  
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/universal-darwin11.0`

In the shell I type: gem env

`RubyGems Environment:  
  - RUBYGEMS VERSION: 1.8.10  
  - RUBY VERSION: 1.9.2 (2011-07-09 patchlevel 290) [x86_64-darwin11.0.1]  
  - INSTALLATION DIRECTORY: /Users/Air/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1  
  - RUBY EXECUTABLE: /Users/Air/.rbenv/versions/1.9.2-p290/bin/ruby  
  - EXECUTABLE DIRECTORY: /Users/Air/.rbenv/versions/1.9.2-p290/bin  
  - RUBYGEMS PLATFORMS:  
    - ruby  
    - x86_64-darwin-11  
  - GEM PATHS:  
     - /Users/Air/.rbenv/versions/1.9.2-p290/lib/ruby/gems/1.9.1  
     - /Users/Air/.gem/ruby/1.9.1  
  - GEM CONFIGURATION:  
     - :update_sources => true  
     - :verbose => true  
     - :benchmark => false   
     - :backtrace => false  
     - :bulk_threshold => 1000  
  - REMOTE SOURCES:  
     - http://rubygems.org/`

I can see that irb is loading the wrong Ruby version and loading the wrong Gem path. Can someone help understand how do I fix this. I am using rbenv for ruby version management not sure how that plays into things. Advice?

Once installed ruby using rbenv.

Have you rebuilded the shim binaries using the command

$ rbenv rehash

Make sure you are setting your path correctly and initializing rbenv in the shell you are using.

I've added the following lines to my .bash_profile:

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

I had the problems you are exhibiting until I remembered to do this.

Also remember to set your global rbenv version of ruby
