python language server not working

Problem Description

No linting and pls just spins on the status line. I know this issue has been addressed in subsequent releases, but I am stuck with only being able to use packages from Anaconda’s main channel, which is woefully slow to update packages to newer versions.

If there were lines of code that needed to be altered or module(s) that needed to be updates, could you please point me to the link that might provide me with a solution so I can try to fix this manually (aka a backport fix would be appreciated).

Best regards

Many thanks to the two of you. I will give a few things a try… besides… who makes coding errors anyway 😉

I think from Spyder 5.1.5 to the current release 5.3.1 quite some work has been done related with the Python Language Server and not only over the Spyder side but also over the python-lsp-server (its current version is 1.4.1) and some plugins like pyls-black (its current version is 1.2.1).

Maybe you could try to edit the env where Spyder is intalled setting the minimum required versions for the python language server related packages as they were in the setup.py for Spyder 5.1.5: https://github.com/spyder-ide/spyder/blob/v5.1.5/setup.py#L203

Also, if it is possible for you to create a Spyder installation using Python 3.7.x that works without issue maybe doing a diff between the packages version installed with that Python version vs the versions installed when using Python 3.9 could give you some hints about what packages versions could help making the Python language server work.

If you can’t use the conda-forge channel or even pip (creating an env with only python from conda and then installing the rest using pip), I think there is not much that we can help, sorry 😕

About Anaconda, we don’t know either, actually some Spyder dependencies like QtConsole got updated on the default channel and that creates issues too since 5.1.5 is incompatible with recent version of those dependencies a no upper constraint was added so that ends up in issues related with incompatibilities 😕
