ruby 2.7.0 macos 10.14 and 10.15

When starting my rails project I experience this crash. I haven't been able to narrow it down to anything.

Did some more debugging and no longer think this is from listen - the stack trace just so happens to land there sometimes.

hey @jjb, what was your issue in the end? I'm facing the same log right now.

jjb commented 1 year ago

@nickbullock

I wish I knew/remembered! Hasn't happened in a long time. I'm on a newer ruby version now. Compiling on MacOS ARM may have been part of the problem.

This worked for me
