Could not find thread_safe-0.3.0 in any of the sources

Answer 1

I was experiencing the same problem.

The thread_safe gem version 0.3.0 has been yanked now from Ruby Gems: http://rubygems.org/gems/thread_safe/versions

So you might want to specify a different version in your Gemfile, or you can point the Gemfile directly to GitHub.

I solved the problem with this line in my Gemfile:

gem 'thread_safe', '0.2.0'
