Error installing Ruby 3.1.2 on macOS 12.5

Question

I'm trying to install Ruby 3.1.2 on macOS 12.5, using chruby as my version manager.

Running ruby-install ruby, I get this error:

>>> Extracting ruby-3.1.2.tar.xz to /Users/justin/src/ruby-3.1.2 ...
/usr/local/bin/../share/ruby-install/util.sh: line 56: xzcat: command not found
/usr/local/bin/ruby-install: line 46: cd: /Users/justin/src/ruby-3.1.2: No such file or directory
>>> Regenerating ./configure script ...
autoreconf: error: 'configure.ac' is required
!!! Configuration of ruby 3.1.2 failed!

I'm not quite sure how to troubleshoot this. Anybody have some tips for me?

Answer 1

There seems to be an issue in ruby-install tracking this.

I appears that ruby-install currently does not explicitly depend on xz as a dependency although they are required for chruby and ruby-install. Until the new version of ruby-install is fully available on homebrew, you can manually install the xz package with

brew install xz

to make sure xz (and thus the xzcat executable) are available on your system. Afterwards, you should be able to install your Ruby version.
