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.

Answer 1

Try updating your Gemfile to use json@1.8.2 instead of 1.8.1 - according to this thread Ruby 2.2.x is incompatible with json 1.8.1 .

1.8.2 should be functionally similar and not affect any of your other dependencies.

You can also run bundle update json to let bundler try to fix it for you - but that may put you at a much later version than 1.8.2 , I'm not sure.

No harm in trying a couple things and reverting your changes.
