Tests fail when ran locally on M2 mac

[lewisl9029]

Hi there! Earlier this week I made a fork of SWC to work on some custom functionality that wasn't yet supported by the new WASM plugin system. I did manage to get the custom functionality working, but I also discovered that the entire test suite in https://github.com/swc-project/swc/blob/main/crates/swc/tests/exec.rs ends up failing when I run it locally with errors that look like this:

I'm pretty new to Rust, but I tried to do some googling for the "Lazy instance has previously been poisoned" message, but wasn't able to find a solution.

Any ideas what could be causing this?

I'm running on a M2 Macbook Air, and set up the repo using the steps in: https://github.com/swc-project/swc/blob/main/CONTRIBUTING.md

Let me know if there's anything else I can help with to figure this out!

You have to post the first error message. Only the first one has useful error message

Ah ok, the first one does look like it has a different message, here's the full output when I run just that one test:

Usage Error: The nearest package directory (/Users/lewis/Develop/lewisl9029/swc/packages/swc-helpers) doesn't seem to be part of the project declared in /Users/lewis/Develop/lewisl9029/swc.

- If /Users/lewis/Develop/lewisl9029/swc isn't intended to be a project, remove any yarn.lock and/or package.json file there.
- If /Users/lewis/Develop/lewisl9029/swc is intended to be a project, it might be that you forgot to list packages/swc-helpers in its workspace configuration.
- Finally, if /Users/lewis/Develop/lewisl9029/swc is fine and you intend packages/swc-helpers to be treated as a completely separate project (not even a workspace), create an empty yarn.lock file in it.

It is an official GitHub mail - mine was a push notification from mobile.
There was an attempt to scam 50 developers :D
