Hi guys,

Does anybody know how to fix this error? I'm trying to install using rbenv different version of ruby and it keeps failing :(

It's a common error but I'm not sure what causes it. My best guess: you have migrated your Homebrew installation from an Intel Mac, but now you have an M1/M2 machine. The libraries that were ported from the old system are compiled for the wrong architecture. You could try brew reinstall readline and see if that helps. If not, you could try reinstalling or otherwise migrating Homebrew completely from /usr/local (where it used to be on Intel Macs) to /opt/homebrew, its default location on M1/M2 machines.

Same problem here, any solution?

I have tried with both arm64 & i386 architecture but nothing works, i don't know what's going wrong.
