I am getting the following error when doing bundle install

Make sure that `gem install couchbase -v '1.3.3'` succeeds before bundling.

Now, i have not included this gem in the Gemfile, so it's coming from some dependency. How can i figure out which gem is dependent on this couchbase gem?

Since bundle install is failing and I don't have Gemfile.lock to figure out this dependency.

gem dependency (with no args) should show you all gems from current Gemfile with their dependencies.

Edit:

You can also do gem dependency -R (or just dep insted of dependency) if you want to find out which gems use specific (or all) gems.

For deeper dependencies I'd parse output (regex maybe?) of first gem dependencies, pick gem's names and call gem dep on each of them, but that's just a loose idea.
