Unable to activate rails 3.0.1 because of bundler version conflict
bundler, ruby-on-rails, rubygems
Solution
You may need to update to bundler 1.1.4.
`gem update bundler`
should do the trick.
Problem
so I run: ``` $ gem install rails --version 3.0.1 Successfully installed rails-3.0.1 1 gem installed Installing ri documentation for rails-3.0.1... Installing RDoc documentation for rails-3.0.1... ``` then I get the error: ``` $ rails -v /usr/local/rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/specification.rb:1637:in `raise_if_conflicts': Unable to activate rails-3.0.1, because bundler-1.1.4 conflicts with bundler (~> 1.0.0) (Gem::LoadError) from /usr/local/rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/specification.rb:746:in `activate' from /usr/local/rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems.rb:1232:in `gem' from /usr/local/rvm/gems/ruby-1.9.3-p125@rails3tutorial/bin/rails:18:in `<main>' from /usr/local/rvm/gems/ruby-1.9.3-p125@rails3tutorial/bin/ruby_noexec_wrapper:14:in `eval' from /usr/local/rvm/gems/ruby-1.9.3-p125@rails3tutorial/bin/ruby_noexec_wrapper:14:in `<main>' ```
