Setting up env, OSX rbenv and bundle battle

So i have just swapped over to mac from ubuntu and setting up the env has not been as easy as promised.

this is the process i followed.

installed xcode - then went into the prefrences and downloaded the command line tools

then verified that the right version was installed, by running gcc --version

i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

then installed homebrew $ ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
ran brew doctor and this is what i get

Your system is ready to brew.

5.installed git brew update + brew install git

6.linked my pc to my git account via ssh

7.installed Rbenv

$ brew update
$ brew install rbenv
$ brew install ruby-build

added eval "$(rbenv init -)" to my .bash_profile file

ran rbenv install -list to see all the versions i could install and then ran
```
$ rbenv install 1.9.3-p327
$ rbenv global 1.9.3-p327
```
(i should have rehashed rbenv but i forgot) i then ran gem install bundler

then went into one of my repo's and ran bundle install which blew up with errors

Gem::InstallError: better_errors requires Ruby version >= 1.9.2.
An error occurred while installing better_errors (0.7.0), and Bundler cannot continue.
Make sure that `gem install better_errors -v '0.7.0'` succeeds before bundling.

ran ruby -v and saw that it was on 1.8.7 "balls" - i exclaimed

to remedy this i did the following rbenv rehash
ruby -v and got ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-darwin12.3.0] then high fived myself

then tried to run bundle and the same error comes up ??

$ which bundle
/usr/bin/bundle

$ which gem
/Users/fortknokx/.rbenv/shims/gem

so this is now where i stand confused as heck. as i said this is my third day using mac and i am pretty new to understanding the $PATH i am sure that i made a foul up somewhere. any advice i am open to.

ps this is what i have in my .bash_profile

export PATH="/usr/local/bin:/usr/local/bin/sublime:~/bin:$PATH"
eval "$(rbenv init -)"

Solution

The problem seems to be that you're using a system ruby installed bundler, and not one installed with your rbenv ruby.

Run ruby --version to make sure your rbenv ruby is active, then run gem install bundler followed by rbenv rehash and then try reinstalling your gems and see if that works.
