This is a known problem when you use the pip.exe command to upgrade pip, because Windows is unable to replace a running executable. It's not practical to remove the error, which is why the documented way of upgrading pip is to use py -m pip install -U pip, not using the pip command directly.

[pradyunsg]

Please use py -m pip or python -m pip to upgrade pip. This issue will be fixed in the next pip release, but you'll only see this upgrading from 22.1 to a newer version. L

[pfmoore]

@pradyunsg Did I miss a fix for this getting applied? Do you have a link?

[uranusjr]

I think it’s #10560? Not yet merged. This would make the command fail outright instead of only erroring out near the end.

[pradyunsg]

Well, I just went ahead and merged #10560 now. I was pretty sure that we'd land that in time for the release next month, hence the choice of words. 😄

[pfmoore]

Ah, I see. Yes, that makes sense (I was thinking that we'd somehow managed to let pip actually upgrade the in-use wrapper, which I was pretty sure I would have noticed if we had 🙂)

[pradyunsg]

No no, I just fixed the check I'd added years-ago, that got broken because newer Windows versions behave differently. :)
