Closed Rodrigoplp closed 3 weeks ago

Rodrigoplp commented 3 weeks ago

After installing Tahoe-LAFS with uv add tahoe-lafs and running .venv/bin/tahoe --version, the following error occurs:

This could be related to the problem with the package attrs, which shadows Python's attr.

The Twisted/klein project seems to have solved this problem by writing a custom provides function: https://github.com/twisted/klein/pull/764.

Happening with Python 3.12.

Fixed with (using PIP):

pip install -U pip setuptools wheel && \
pip install attrs==23.2.0 'cryptography<42' tahoe-lafs

Or (using UV):

uv lock --upgrade-package setuptools
uv add wheel
uv add 'attrs==23.2.0'
uv add 'cryptography<42'
