I had the same issue recently. Check your pry gems by typing the following into the terminal:

gem list pry

This should return all of your pry related gems. I fixed the issue by uninstalling all of the extra pry gems (e.g., pry-nav). The one that was causing the issue for me was the pry bye-bug gem.

gem uninstall pry-nav fixed it for me.
