Greetings! The other day, I was having trouble installing a lower version of Ruby using ASDF and after trying to solve around a bit, I figured out a solution. This solution might not work for everyone, but I wanted to share it in case it helps.

If you need to install a lower version of Ruby using ASDF and you are using a Mac OS and a chip M1:

asdf install ruby 2.5.6

and get this error:

To fix it, you need to run the following command:

RUBY_CFLAGS="-w" asdf install ruby 2.5.6
