Struggling to install Ruby 3.2 on M1 mac - cannot load such file -- psych

[whomwah]

Morning,

I'm unable to install 3.2 on my M1 mac this morning. I've tried various ruby-build solutions with no luck. I think the project doesn't use ruby-build though.

Here's my output when making sure libyaml is installed too (rbenv/ruby-build#2118 (comment)).

> brew install libyaml
...
> brew --prefix libyaml
/opt/homebrew/opt/libyaml

> frum install 3.2.0

To eliminate this warning, please install libyaml and reinstall your ruby.
uh-oh! RDoc had a problem:
cannot load such file -- psych

run with --debug for full backtrace
make: *** [rdoc] Error 1

Anyone have any tips? Do I need to use a RUBY_OPTS explicitly to point to libyaml

Also tried:

❯ frum install 3.2.0 --with-libyaml-source-dir=$(brew --prefix libyaml)

@whomwah Have you found out where is the problem? I have same issue :(

[simon-caignart]

same problem here 😒

[kjayma]

@whomwah This worked for me (see apple.stackexchange):

$ export CPATH=/opt/homebrew/include
$ export LIBRARY_PATH=/opt/homebrew/lib

Still trying to sort out the panic issue when using the --with-jemalloc option.

i've solved this problem as below:

1. Set the env variables for C/C++ libraries in ~/.zprofile (reference: apple.stackexchange.com)

   export CPATH=$(brew --prefix)/include
   export LIBRARY_PATH=$(brew --prefix)/lib

2. Set the Ruby configuration options env variable in ~/.zprofile (reference: asdf-ruby/issues/328)

   export RUBY_CONFIG_OPTIONS=--with-openssl-dir=$(brew --prefix openssl@3)

3. Install the Ruby

   frum install {version} $RUBY_CONFIG_OPTIONS

though, i think this is just a temporary workaround.

For me the ''proper'' fix that didn't involve messing around involved installing pkg-config before attempting to install ruby.
brew install pkgconfig
Hope that helps someone, sorry for the necro :)

This solution also worked for me. Thanks a lot!

I'm installing ruby on a brand new M4 mac.

I had the poorly documented error Can't build Ruby: make failed: file2lastrev.rb: does not seem to be under a vcs: .

brew install pkgconfig was the only solution that worked for me.
