Rails 3 - Could not find rake-0.9.2 in any of the sources (Bundler::GemNotFound)

Question

I would like to ask you about bundler… if I run command "bundle list", so I will get list of gems and is there "* rake (0.9.2)", but if I move my app to server, I am getting error Could not find rake-0.9.2 in any of the sources (Bundler::GemNotFound) — but this gem is in bundler… what could be wrong?

Answer 1

You should package the gems with the application.

rm -rf Gemfile.lock then re-run bundle install
