MacOS builds failing, actions/setup-node does not fix issue

[jakebeal]

Describe the bug

Issue #578 was closed with a suggestion that it could be addressed through use of actions/setup-node.

This suggestion does not appear to work: here are failures with both Node 18 and Node 20.

In these transcripts, note that the execution of setup-graphviz appears to ignore the copy of Node.js that is set up via setup-node, as brew installs its own node package (before ultimately failing).

The failure is now actually inside of setup-graphviz, rather than due to Node not being set up before, and does appear to be linked to the outdated packages used by setup-graphviz.

The failure can be found in other projects as well.
Examples:

• https://github.com/jakebeal/kagome/actions/runs/8337292144/job/22815789124 (fork: last run on root project was before failures began)
• https://github.com/ModECI/MDF/actions/runs/8347579020/job/22847503522.

Please do not close this issue until there is actually a verifiable fix this time.

I am hitting the same failure mode seen in the second failure link in this issue:

To force the link and overwrite all conflicting files:
  brew link --overwrite python@3.12

To list all files that would be deleted:
  brew link --overwrite python@3.12 --dry-run

Possible conflicting files are:

Looks like something to do with homebrew Python installation vs. existing system installation?

  private async brewInstall() {
    const skipBrewUpdate = getBooleanInput("macos-skip-brew-update");
    if (skipBrewUpdate === false) {
      await exec("brew", ["update"]);
    }
    await exec("brew", ["install", "graphviz"]);
  }

Well... given this is all this action really does, it's an issue with the macos-latest worker itself? ¯\_(ツ)_/¯

[jakebeal]

@vkottler So far as I was able to diagnose in #578, the problem is that setup-graphviz only does one of the two standard brew update commands. That ends up leaving it with worse information than if it doesn't update at all.

I submitted a possible patch in #579, but it was declined by the maintainers because they didn't think this issue was real at the time. I am hoping that they will take it more seriously now that multiple projects are reporting the same issue.

[vkottler]

I was able to fix my issue by:

• Switching to https://github.com/tlylt/install-graphviz/tree/main
• Doing graphviz install/setup before Python

Wonder if something similar might work for you @jakebeal ?

[jakebeal]

This looks to be equivalent to my current patch, which is to run ts-graphviz/setup-graphviz with the "mac disable update" setting on.

I would prefer not to switch away from ts-graphviz if I can, since this project has historically been stable and well-maintained, but my choice in the end will depend on the future choices made by the maintainers of the this project.

Thank you for the information.

We have not been able to capture the exact situation yet, but it seemed to have affected us more than we anticipated.

I will try to find time to work toward a solution.

Thank you for your continued cooperation.
