###### WARNING:
       Removing `Gemfile.lock` because it was generated on Windows.
       Bundler will do a full resolve so native gems are handled properly.
       This may result in unexpected gem versions being used in your app.
       In rare occasions Bundler may not be able to resolve your dependencies at all.
