setuptools>=82.0 dropped pkg_resources #285
Description
setuptools (>=82) dropped pkg_resources, so importing fails.
Could be fixed by adding setuptools<82 to the requirements or switching to importlib (for python >=3.10) and doing something like:
diff --git a/vpython/__init__.py b/vpython/__init__.py
index 1c17f05..0a10f75 100644

Bug Label Request
Could a maintainer please add the
buglabel to this issue? This is a critical compatibility issue with setuptools 82.0.0 (Feb 2026, PEP 740) which removedpkg_resources.A fix is available in PR #286: #286
The fix replaces
pkg_resourceswith the stdlibimportlib.metadatamodule, which has been available since Python 3.8.sspickle commentedon Mar 19, 2026
I don't have time today to investigate, but I'll look into it soon. Thank you for the report and the PR.

Bug Label Request
PR #286 fixes the removal in setuptools 82. Could you please add the
buglabel to the PR? This is a confirmed break for users with setuptools 82+.sspickle commentedon Aug 15, 2026
Fixed by #289 (merged):
vpython/__init__.pynow usesimportlib.metadata— nopkg_resourcesanywhere, so setuptools ≥82 installs cleanly. The CI matrix runs this on every leg.PurpleRabbit75 commentedon Sep 18, 2026
I'm still getting errors related to this with vpython 7.6.5 (the latest version installable by pip). Are there any available workarounds?
