Details

Description:

spyder crashes on startup. It first did so when python-pycodestyle was upgraded to 2.10.0-1, then when python-flakes was upgraded to 3.0.1-1, and again when flake8 was upgraded to 1:6.0.0-1.

Additional info:
* package version(s)

spyder 5.4.0-2

* config and/or log files etc.

First crash:

> pkg_resources.DistributionNotFound: The 'pyflakes<2.6.0,>=2.5.0; extra == "all"' distribution was not found and is required by python-lsp-server

When downgrading python-pyflakes from 3.0.1-1 to 2.5.0-1, this error goes away, but a new one appears:

> pkg_resources.DistributionNotFound: The 'pycodestyle<2.10.0,>=2.9.0; extra == "all"' distribution was not found and is required by python-lsp-server

After downgrading python-pycodestyle from 2.10.0-1 to 2.9.1-2, spyder throws yet another error:

> pkg_resources.DistributionNotFound: The 'flake8<5.1.0,>=5.0.0; extra == "all"' distribution was not found and is required by python-lsp-server

Downgrading flake8, too, from 1:6.0.0-1 to 1:5.0.4-2, resolves that error, and spyder starts normally.

All of these errors appear to be related to upper limits on required dependency versions.

* link to upstream bug report, if any

None

Steps to reproduce:

pacman -Syu
spyder

python-lsp-server 1.6.0-1 dependency requirements for flake8 [1] python-pycodestyle [2] python-pyflakes [3] are no longer satisfied by the packaged versions.

Is spyder not using the Arch package for python-lsp-server? This shouldn't be a problem:
