1 year ago @stevecheckoway Yeah, sorry for the trouble. Psych 5 is indeed a challenging thing to install. We have a few options ...
The easiest thing to do might be to edit your local Gemfile for now to remove Psych. You may still need to explicitly pin it to ~> 4.0 to prevent an upgrade to Psych 5, though.
So the next option might be to remove both rdoc and psych from your Gemfile, then you'll get and use whatever version your Ruby was shipped with. If that works for you, I can create a bundler "group" for documentation and you can turn it off permanently on your local machine. Want to give that a try with me?

Commit c7a780298614c81f3dc5925e2b0c23b836e1c6e0 updates the psych requirements from 4.0 to 5.0 and this is broken on macOS. There's more context here.
The basic problem is that psych no longer bundles libyaml and macOS doesn't come with libyaml nor does it have a system package manager that can be used to install it. It seems the expected situation is to use homebrew to install the library system wide.
It's possible to install the psych gem by passing an option pointing to the libyaml source directory, but this is broken on M1 macs. After I filed a bug report, a pre-release version of psych was created and pushed to rubygems. I can successfully install this version of psych, but that doesn't help with building Nokogiri any longer as
bundle installstill tries to install the non-prerelease version of the gem.

I tried using rvm but—after undoing all the damage the installer does to my shell dot files—it turns out that rvm depends on a global installation of homebrew.
Suggestions welcome.
