Looks like the cache disappeared, which AVA isn't expecting. How did you install the new dependencies? npm ci?

[OmgImAlexis]

yarn add in another terminal window.

[novemberborn]

Thanks, I guess that cleans up node_modules too. Maybe the issue is just that the .cache/ava directory is gone, which should be easily detected and dealt with.

Have an issue in github action. Not in watch mode, works fine in local machine.

@towry that action uses Node.js 10.0.0, AVA requires 10.18.

[Lunchb0ne]

Is anyone working on this issue right now?

[novemberborn]

@Lunchb0ne no, but I'll assign it to you since it sounds like your keen 😄

[Lunchb0ne]

Cool, I'll try my best

[Lunchb0ne]

Okay, weird, I can't seem to reproduce the issue, but that might be because I'm just using boilerplate code. I'll try with some other project that uses ava for testing.

[novemberborn]

@Lunchb0ne you may want to try a project that uses @ava/babel, which writes to the cache directory.

[Lunchb0ne]

Can you suggest any small projects that I can use for testing?

[novemberborn]

If you write a test.js file and enable babel: true in the configuration, with @ava/babel installed, that should do it.

[Lunchb0ne]

Okay, I'll try it
