Hi,

I upgraded my macOS with M1 chip from 12.6.0 to 12.6.1. I did not know that the default Ruby would change from 2.6.8 to 2.6.10. Now my iOS app which requires pod install does not work with Ruby 2.6.10, error with gems/ffi-1.15.5.

I have rbenv on the Mac but I cannot "rbenv install 2.6.8" from ruby GitHub, error with homebrew.

Would it work if I use another M1 Mac with 12.6.0 and rbenv and exec "rbenv install 2.6.8" there and then copy the resulting version to my ~/.rbenv/versions?

Then "rbenv local 2.6.8" so I can bypass 2.6.10?

Thank you.

This does not work as gems/ffi still ref 2.6.10 and not 2.6.8 as assigned by "rbenv local 2.6.8".
