Bundler issues in installing rails on ubuntu

Question

I have installed ruby 1.9.3 using rvm and after doing gem install rails, it says gem successfully downloaded, but when I type rails -v it gives me the following error: Unable to activate rails-3.0.1, because bundler-1.5.1 conflicts with bundler (~> 1.0.0) (Gem::LoadError)

How do I fix this?

Answer 1

do this:

rvm @global do gem uninstall bundler -ax
gem install bundler -v '~>1.0.0'

this will remove the globally installed bundler (available for all gemsets on this ruby) and install compatible local version only for current gemset.
