Can't install psych 5.0.1 in macOS on Apple Silicon

[dentarg]

I have libyaml from Homebrew installed. It works when running Ruby with Rosetta 2 (arch -x86_64 /bin/zsh).

Issue seems to be checking for yaml_get_version() in -lyaml... no for arm64.

Details:

arm64: gem install --verbose psych

arm64 $ gem install --verbose psych

I recommend to use Ruby 3.1.3 because 3.1.2 is not working correctly with Ventura/Xcode14 and Apple Silicon.

[dentarg]

The failure is the same with Ruby 3.1.3 and Apple Silicon (+ I'm not using Ventura; this is macOS 12.6.1)

There is no idea to resolve it. Maybe it related with --with-yaml-dir or other options.

It seems your environmental issue.

[jejacks0n]

Literally just ran into this same issue on Ventura, M1. With ruby 3.0.5p211, and ruby 3.1.3p185

libyaml appears to be available...

❯ brew info libyaml

And I can install version ~4 of psych.

And in the mkmf.log:

Interestingly, I see a similar issue when trying to install ruby 3.2.0.rc1, where I was going to check as well:

uh-oh! RDoc had a problem:
cannot load such file -- psych

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

EDIT: Maybe I'm not seeing the same thing. It looks like for me libyaml yaml.h is just not being found, and I've tried providing it in a couple different ways when trying to build the native extension.

[dentarg]

@hsbt It works if I do brew uninstall libyaml for x86_64

I noticed this line from mkmf.log posted above: ld: warning: ignoring file /usr/local/lib/libyaml.dylib, building for macOS-arm64 but attempting to link with file built for macOS-x86_64

I think this should just work as it does work using 3.2.0-preview3 when libyaml is installed for both arm64 and x86_64

Is there some recent change to mkmf.rb that should be backported?

[Sairav]

I was facing the same issue ->

An error occurred while installing psych (5.0.0), and Bundler cannot
continue.
Make sure that `gem install psych -v '5.0.0' --source 
before bundling
In Gemfile:
  rdoc was resolved to 6.4.0, which depends on
    psych

I believe after psych added a runtime dependency on stringio from ver 5.0.0 starting December 5th 2022 , we are facing the issue. If I rollback to psych 4.0.6 , it's working fine for me.

[hsbt]

@Sairav No, It's different issue. You should install libyaml-dev for resolving it.

[hsbt]

@dentarg I don't know what changes of mkmf related your issue.

[Sairav]

Thanks @hsbt , my issue was resolved by installing libyaml-devel , working with latest ver psych 5.0.1 .

If it helps anyone , I was running Oracle Linux 7 Slim , command used -

• yum --enablerepo=ol7_optional_latest install libyaml-devel

@colby-swandale Can you try with gem i paych -- --with-yaml-dir=$(brew --prefix libyaml)?

[chriskol]

Don't have an M1/silicon but getting the same thing on my MBP

[iiiw]

brew reinstall libyaml worked for me (M2, MacOS Ventura, ruby 3.1.3p185)
