ts-patch sometimes™ fails when used in a GitHub pipeline

[felabr]

Hello,

we are experiencing an issue with ts-patch in our project. Sometimes the build pipelines on GitHub fail during the build step when ts-patch tries to delete some lock files that seem to be missing. Everything works fine locally, and it usually works fine on GitHub, too.

We haven't built anything fancy, it's just yarn build, wich runs tspc --project tsconfig.build.json, and the config file has basic options like outDir and baseUrl and enables typescript-plugin-styled-components.

So, I'm a bit lost trying to figure out what's going on here, and I'd really appreciate someone pointing me in right direction.

Is there maybe a way to make ts-patch ignore missing lock files when it just wants to delete them anyway?

Thank you

This is the error message we are getting:

Was there an answer to this or a follow up or a workaround?

Hi @mannycarrera4,

I noticed this happens when we run two builds in parallel for cjs and es, like this: tspc --project tsconfig.build.cjs.json & tspc --project tsconfig.build.es.json.

As a workaround we now run them one after the other, like this: tspc --project tsconfig.build.json && tspc --project tsconfig.build.es.json (with && instead of &).

So I assume the names of the lock files are sometimes not unique when we do parallel builds.

I've created PR #165 that would simply ignore missing lock files that may already have been deleted. But if the above assumption is right it would probably be better to ensure unique lock file names even in parallel builds.

Ah thanks for getting back to me! Yeah we had to do the same, remove --parallel from our build script and that seemed to have worked.
