Bundler::GemNotFound: Could not find rake-10.3.2 in any of the sources

bundle install --path vendor/cache

generally fixes it as that is the more common problem. Basically, your bundler path configuration is messed up. See their documentation (first paragraph) for where to find those configurations and change them manually if needed.

I solved that deleting the Gemfile.lock

I think rake must be preinstalled if you want work with bundler. Try to install rake via 'gem install' and then run 'bundle install' again:

gem install rake && bundle install

If you are using rvm ( http://rvm.io ) rake is installed by default...
