@caseyprovost I found the same problem and 👍 the PR (once you fix the whitespace ;)

[johnpaulashenfelter]

For those that care, the issue happens with the brand new release of pry, v0.13, which has a lot of changes, one of which is this one which seems to be undocumented.

For the time being, you can add

  gem 'pry', '< 0.13'

do you Gemfile assuming you're using this in a Rails app.

Closing in favor of #958.
