Installing ruby but getting error "linker command failed with exit code 1"

Question

I'm building a GitHub Pages site and trying to install Ruby for my Mac as described here. When I run ruby-install ruby , I get the following:

linking shared-object -test-/arith_seq/extract.bundle
Undefined symbols for architecture arm64:
  "_rb_arithmetic_sequence_extract", referenced from:
      _arith_seq_s_extract in extract.o

clang: error: linker command failed with exit code 1 (use -v to see invocation)

make[1]: *** [ext/-test-/arith_seq/extract/all] Error 2
make: *** [build-ext] Error 2
!!! Compiling ruby 3.1.2 failed!

I'm totally unfamiliar with Ruby and don't know how to make any sense of this. Any ideas? Thanks

I was running into same issue as you after following the Jekyll guide.

Christian from your comments supplied a very detailed solution and explanation as to what's caused it.

After updating to macOS 12.6 or 13.0, you might still be able to install 2.7.x and 3.x versions of Ruby with rbenv or asdf. With ruby-install, you’ll need to add the --enable-shared flag. Once 2.7.7 and 3.1.3 are released, you should no longer need to add any flags.

Install for me on Mac OS 12.6 worked with ruby-install 3.1.2 -- --enable-shared
