The test failure is probably unrelated, but maybe you can look into it for a separate PR? We usually hold changes until CI goes green.

Use `bundle info [gemname]` to see where a bundled gem is installed.

Failed examples:

rspec ./spec/integration/omniauth/integration_spec.rb:33 # omniauth works

Based on the error, most likely nothing to do with typos changes. I'm not familiar with Ruby, hence I doubt I can help much.

I fixed the integration test failures in #581.
