Pyright 1.1.405 cannot resolve extension module symlinked to virtualenv #10906
Description
Describe the bug
We have a virtualenv composed of symlinked packages (using uv2nix but that's irrelevant). After upgrading from 1.1.404 to 1.1.405 a package import is no longer recognized. It looks like, symlinking files is the issues, symlinked code directories work fine.
Code or Screenshots
- Using
cpp_demangleas an example. This package puts its extension immediately undersite-packages(.venv/lib/python3.11/site-packages/cpp_demangle.cpython-311-x86_64-linux-gnu.soin my case). Also using pyright 1.1.404, as the last working version:
❯ python3 --version
Python 3.11.13
❯ python3 -m venv .venv
❯ source .venv/bin/activate
❯ pip install cpp_demangle pyright==1.1.404
