[emschult]

I am trying to download ruby 2.5.1 and have repeatedly run into failures. I have tried a number of trouble shooting techniques. Any help would be greatly appreciated!!

Thank you for commenting. I followed your guidance and ran:

$ sudo rm -rf /Library/Developer/CommandLineTools
$ xcode-select --install
$ sudo xcode-select -s /Library/Developer/CommandLineTools

It ran without issues. I tried to download again using

rbenv install 2.5.1 and got a failure again:

Ruby 2.5 is not supported on M1 macOS.

Ruby 2.5 is not supported on M1 macOS.

Actually you have to install natively
You try this command to install 2.5.x versions
-$ RUBY_CFLAGS=-DUSE_FFI_CLOSURE_ALLOC arch -arm64 rbenv install 2.5.3

@hsbt
Do you know of any Ruby builds that are compatible?

I was planning to use this computer to do App Academy. Any idea if there is a good syntax change cheat sheet between versions?

Thank you for all the help!!

[hsbt]

Do you know of any Ruby builds that are compatible?

Ruby 2.7.2+ and Ruby 3.0.0.

@hsbt
Thank you very much for the help! After a bit more troubleshooting I was able to successfully install:
2.7.2 & 3.0.0

Excited to start learning. Thank you again!!

For any beings from the future, use this command to install on M1 Mac (I'm using asdf but works for rbenv as well):
RUBY_CFLAGS="-Wno-error=implicit-function-declaration" asdf install ruby 2.5.1
