Bundler errors in an environment with Rails 3.1 gem installed

Question

I have Rails 3.0.10 and 3.1 installed because I'm trying to use both for two different projects.

In my Rails 3.0.10 project, I have the following at the top of my Gemfile:

gem 'rails', '3.0.10'

However, after starting up, bundle install; bundle exec rails --versionI get the following:

/Users/bradley/.rbenv/versions/ree-1.8.7-2011.03/lib/ruby/gems/1.8/gems/bundler-1.0.21/lib/bundler/runtime.rb:31:in `setup': You have already activated activesupport 3.1.1, but your Gemfile requires activesupport 3.0.10. Using bundle exec may solve this. (Gem::LoadError)

Any ideas? Obviously, I am already using bundle execand bundle show rails; bundle show activesupportto confirm that I have to use the correct versions of gemstones. Should I just uninstall Rails 3.1?

Answer 1

I ran into the same problem.

Even when I explicitly specify the version of activesupport to use in my Gemfile:

gem 'rails', '3.2.9'
gem 'activesupport', '3.2.9'

it still gives me this error when I run bundle exec rails s:

/home/tyler/.rvm/gems/ruby-1.9.3-p194@global/gems/bundler-1.0.18/lib/bundler/runtime.rb:31:in `block in setup':
You have already activated activesupport 3.2.10, but your Gemfile requires activesupport 3.2.9. Consider using bundle exec. (Gem::LoadError)
