Unhelpfull error

[Evanion]

Hello
I have tried in both pwsh and bash on windows 11 to create a patch, but I get a cryptic error that doesn't really give me any info on why it failed.

 npx patch-package @remix-run/dev
patch-package 8.0.0
• Creating temporary folder
• Installing @remix-run/[email protected] with npm
{
  status: 1,
  signal: null,
  output: [ null, null, null ],
  pid: 42836,
  stdout: null,
  stderr: null,
  error: null
}

C:\dev\LHB.Frontend\node_modules\patch-package\dist\makePatch.js:395
        throw e;
        ^
{
  status: 1,
  signal: null,
  output: [ null, null, null ],
  pid: 42836,
  stdout: null,
  stderr: null,
  error: null
}

Node.js v20.12.2

I have used the tool as late as last week in this repo, so I don't understand why this fails.
Any ideas on how I can futher debug this?

This is an artifact of using new yarn versions while patch-package doesn't support for them for patch-generation.

There are PRs that will fix this, however you need it to work now right? I did.

So patch-package can patch just fine with new yarn versions but it cannot generate patches with new yarn versions.

Solution: use npm just for patch generation, add the --use-npm flag at the end

npx patch-package <broken package name here> --use-npm

Edit: I swear that worked one time, but it did not work a second time.

But what did work was temporarily doing a yarn set version 1.22.20 then npx patch-package <busted package> and then reverting the yarn version change 🤷
