Trouble installing on MacOS 13.1 + Ruby 3.2.0 (via rbenv)

[gobijan]

Hi, happy new year and thanks for making this gem :)

I was trying to install it on MacOS 13.1 (22C65) with installed and agreed xcode commandline tools and rbenv ruby 3.2.0 (2022-12-25 revision a528908271) [arm64-darwin22]

Unfortunately I can't get it to install with Ruby 3.2.0. However I can install using Ruby 3.1.2.
Any clue how to fix this?

Here is the output:

❯ gem install readapt

@gobijan Hi, How did you end up solving this? I am having a similar error just on WSL? Thank you.

[gobijan]

I didn't tbh.
I had no time looking deeper into this and use RubyMine for now for convenient debugging.

[zzJZzz]

Thanks for the reply. I'll put this on the backburner for now.

[gobijan]

I just had a look into the code.
Problem is the rb_cData that was deprecated. It has been removed in ruby 3.1 and therefore this code needs to be changed all the way to support newer Ruby versions.

See: https://bugs.ruby-lang.org/issues/18433

[gobijan]

Could be enough to simply replace rb_cData with rb_cObject.
I'll try and might create a PR if successful.

#15

@zzJZzz give it a try and let me know if it works for you.

[gobijan]

Works for me(™)

[megatux]

same here on MacOS Sonoma and Ruby MRI 3.2.2. The above workaround PR seems to work here, too.

Fix released in v2.0.0.

I confirm the rb_cData/rb_cObject issue is resolved.
