pipes was obsoleted in Python 3 (yes, 3.0) and finally removed in 3.13.
You can probably use shlex instead.

Thank you for opening this issue @0-wiz-0! This was fixed by #286, so now we are waiting on a release!

It should be fixed once that release is out!

That's great, thank you! Looking forward to the release.
