Conflicting dependencies in same gem. Bundler could not find compatible version for gem "faraday"

Question

So I am running bundle install, and I get this error:

Bundler could not find compatible versions for gem "faraday":
  In Gemfile:
    google-api-client (= 0.5.0) ruby depends on
      faraday (~> 0.8.1) ruby

    google-api-client (= 0.5.0) ruby depends on
      faraday (0.9.0.rc5)

The way I see this is that one of my gems, the google-api-client -v 0.5.0 has internal conflicting dependencies. How is this possible?

I have tried deleting the Gemfile.lock, I have tried different versions (0.5.0 and 0.6.0) of the google-api-client but nothing seems to help. Anyone knows what is going on here?

Answer 1

I found that this issue was only present in version google-api-client -v 0.5.0 and google-api-client -v 0.6.0 (possibly others). Changing to 0.6.4 solved the issue for me.

Hopefully this will help someone else out there.
