Minimal reproduction URL

https://stackblitz.com/github/namesmt/repro-tsx

Problem & expected behavior (under 200 words)

Alternative github repo because stackblitz could not load for me, idk if it's just me: https://github.com/NamesMT/repro-tsx

Simply run pnpm install, an unexpected file is created along with the folder tsx-0

It does not happen with normal npm

Bugs are expected to be fixed by those affected by it

I can't reproduce this on my end. Can you use GitHub Actions or something to demonstrate it?

[NamesMT]

Hello @privatenumber,

Here is a oneline reproduction using docker run: docker run -it --rm namesmt/images-alpine:node-dev zsh -c "cd home && nlx giget gh:namesmt/repro-tsx repro-tsx && cd repro-tsx && ni && ls && ls tsx-0 && zsh"

Sorry but a screenshot doesn't help. And I don't use Docker.

I need a reproduction env for me to debug and test fixes in. GitHub Actions or any kind of CI would work best.

[NamesMT]

Hello @privatenumber, idk why but for github's default runners I could not reproduce it, but does indeed exists because I could reproduce the issue on my work machine which uses plain Ubuntu,

I have also do more tests and it is indeed reproducible on various docker images: ubuntu, node/node:slim, alpine.

I have also able to reproduce it on my company Gitlab CI with node:alpine image.

For your convenience, I have setup a repo in which I was able to use Github Actions to reproduce it (using docker container action): https://github.com/NamesMT/repro-tsx-action
You could simply fork it and push commits/PR to test.

Thanks a lot.

[privatenumber]

I appreciate it, thanks @NamesMT

I haven't confirmed this, but I believe this is actually pnpm/pnpm#7330

tsx creates a cache directory in os.tmpdir() which implies pnpm in Alpine is returning the current working directory in the env variables.

Will take a closer look later on.

That seems to be it, maybe we can apply a workaround like jiti#123?

If it's rooted in pnpm, then it's not a tsx bug. And I would rather not patch bugs from other tools via tsx.

This is for the same reasons I would relay any Node bugs we get to https://github.com/nodejs/node. Encouraging fixes to be made in the right places maximizes benefit to the community.

Can you verify this is what's causing it by running pnpm with unsafe-perm? https://github.com/pnpm/npm-lifecycle/blob/1e0f149176877f906968a01087cf63290652ccbc/index.js#L100
If so, try opening a PR there.

[NamesMT]

Yes I can verify that running pnpm with unsafe-perm, the issue is not present, thanks a lot for finding the root cause.
Don't have time to open a PR yet but I'll do it when I do and no one has created one specific to it.

Closing as it's a bug in pnpm rather than tsx
