What do you mean by "setting up" What do you mean by "the slather step"? How may I attempt to reproduce your problem? – Esquiline

Are you doing something with gem install? Or with bundle? Are you using rbenv, rvm, or similar? (Why might the system be reporting multiple ruby versions?) – Esquiline

This is the same error I have got while running the unit test case using the fastlane. fastlane [platform_name] tests. @Harry Did you get the solution to your problem? – Discourse
