Hi I see this codebase is 3 years old but still thought to put the issue here as I am following along and coding with the development of the app trying to generate the model comments.
An error occurred while installing json (1.8.1), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.1'` succeeds before bundling.
gem install json -v '1.8.1'
bundle package
gem install bundler -v '= 1.5.1'
bundle update json
