Infinite loading

[nrydanov]

Hello, thank you for adding virtual environment support.

I've just installed latest Pylyzer version from Cargo, added Pylyzer as source for nvim_lsp and I see infinite loading on "checking files...". However, it seems like using pylyzer on single file from terminal works fine.

Problem reproduces for VSCode too.

Useful information:
Pylyzer: 0.0.66
OS: MacOS Sequoia 15.0.1
Python version: 3.10.13
Package manager: Rye/UV
Processor: Apple M1

Any thoughts what can be wrong?

Hey guys! I'm not a maintainer but I ran in a similar issue, turned out that running

$USER /path/to/pylyzer --server

Printed the following errors:

[ERR] ERG_PATH not found
[ERR] ERG_PATH not found
[ERR] ERG_PATH/lib/pystd not found
[ERR] ERG_PATH not found
[ERR] ERG_PATH/lib/core.d not found
[ERR] ERG_PATH not found
[ERR] ERG_PATH/lib/std not found

which was already solved in this issue

So I reinstalled it using the sistems package manager and it did exported the correct environment variables;

So, since you guys are on MacOS, I'd try using homebrew
or following the solution on the issue I said:

If for some reason the files under lib cannot be installed, you can reinstall them using the following method.

• pip reinstall

pip install --force-reinstall pylyzer

• cargo reinstall

cargo install --force pylyzer

• ergup

python3 <(curl -L https://github.com/mtshiba/ergup/raw/main/ergup.py)

Hope it helps

+3 the above solution with reinstalling did not work for me. Running pylyzer from cli is also stuck

[nrydanov]

Didn't helped for me too, Pylyzer is ok with finding env variables or libraries, but still fails to load.

I'm having the same issue. I setup pylyzer through nix shell using 0.0.66 (I made an overlay for it). My CLI is also stuck in a loop forever.

[nrydanov]

@mtshiba Still reproduces on v0.0.67

[agrin96]

Could problem be in using python 3.12 typing features? I've managed to show the parser produces a stack-overflow on my code and its all written with generics and 3.12 typing.

Same problem version 0.67.0 and 0.68.0 too

[nrydanov]

UPD. Some of my old projects using poetry works fine.

[nrydanov]

UPD 2. Found repo with Poetry, where error is still reproduces, so there's probably no dependency between package managers.

Also, if I remove .venv in any of these projects, Pylyzer is not stuck anymore. Looks like specific virtual environment state breaks pylyzer.

I've been having similar issues; fixed the ERG_PATH not found through cargo install erg but still got the infinite loading in e.g. pylyzer app.py.

To debug this, I've pip installed different versions of pylyzer to try them on the same (miniconda) virtual environment and test file.

After trying out versions 0.0.53, 54, 55 and 56, I've tried switching back to the latest version of pylyzer, it now prints errors instead of hanging (it now fails to load modules, but that's another issue entirely) !

I'm assuming there's some sort of dependency or environment variable that used to be set via setup.py and didn't get unset when upgrading.

[mtshiba]

It seems that a bug in the Erg compiler was causing the checker to hang.
I applied a patch to fix the issue and confirmed that it was fixed in some Python packages, but it is unclear whether the problem has been completely resolved.

Not great for a first experience:

Never completes, never does anything. Is there something I am missing here?

[nrydanov]

Sorry, but it still reproduces with UV. Analysis ends only for test.py file located in root folder.

All files in src folder are still hanged forever.
