ERROR: Your bundle is locked to json (1.8.1), but that version could not be found in any of the sources listed in your Gemfile. If you haven't changed sources, that means the author of json
(1.8.1) has removed it. You'll need to update your bundle to a different version of json (1.8.1) that hasn't been removed in order to install.

solution is to:

gem install json -v '1.8.1'
