Crash: error: [Errno 17] File exists with setuptools >= 71.0.2

[albertosottile]

The app bundling process (python ... py2app) crashes with the message error: [Errno 17] File exists: [file path] when setuptools>=71.0.2 is installed.

So far, I have seen the error occurring on

• /build/bdist.macosx-10.9-universal2/python3.10-standalone/app/collect/typing_extensions-4.12.2.dist-info
• /build/bdist.macosx-10.9-universal2/python3.10-standalone/app/collect/tomli-2.0.1.dist-info
• /build/bdist.macosx-10.9-universal2/python3.10-standalone/app/collect/packaging-24.1.dist-info

but I guess this heavily depends on my app.

Reverting setuptools to version 71.0.0 or lower allows to build the app again.

Another workaround might be to add setuptools to OPTIONS['excludes'] but this might be impossible in some app bundles.

I too had the same issue using SetupTools 72.2.0. I reverted back to 70.3.0 and this issue went away. I was building using Python 3.12.5.

I was having the same issue and reverted to 70.3.0, like @jwojcik999, and met with immediate success.

same for me on macOS Sonoma with Python 3.12.5, reverted to 70.3.0 and problem solved

Me too. I had to convince pip-compile to pin setuptools which was annoying, but it did indeed fix the issue.
