  "The running version of Bundler (#{Bundler::VERSION}) does not match the version of the specification installed for it (#{@loaded_spec.version}). " \
  "This can be caused by reinstalling Ruby without removing previous installation, leaving around an upgraded default version of Bundler. " \
  "Reinstalling Ruby from scratch should fix the problem."
