rchiodo · 2023-10-26T23:46:34Z

Ran into the same problem on Pylance v2023.10.50 and it seems to be due to some sort of corrupted cache?
I renamed my workspace directory to a different name and it's no longer crashing.
It would be helpful to know how to reset the cache in case something like this happens.

My cache would be here:
C:\Users\rchiodo.vscode\extensions\ms-python.vscode-pylance-2023.10.41\dist.cache (the dist/.cache folder wherever the extension is installed)

Worth a try to see if somehow that's breaking things, but the callstack on the original poster isn't indicating a read from the cache. So we're not sure what's happening.

d0gkiller87 · 2023-10-26T23:59:47Z

Ran into the same error on Python 3.8.10, Pylance v2023.10.50.

Worth a try to see if somehow that's breaking things, but the callstack on the original poster isn't indicating a read from the cache. So we're not sure what's happening.

I removed my falsely concluded comment about how renaming workspace fixes it. Turned out it was due to that VSCode selected another Python interpreter on my system (3.11.4) by default, which Pylance runs fine with.

rchiodo · 2023-10-27T00:09:52Z

Hmm, the failure indicates the return value of statSync (which is a call into the node fs library eventually) is not returning the correct type of object. This might happen if the site-packages folder has a zip/egg. Which might explain how it works in one environment and not another.

The weird part is we haven't changed that code in a long time, so not sure how it would have worked before. 6 months ago was the last update.

nosas · 2023-10-27T00:12:30Z

Similar issue, although mine "restarts" instead of stopping. Pylance was working fine all day up until 2 hours ago:

It works fine on my python environment with no egg package, but crashes in my pipenv environment which has an egg.

Any debugging advice?

darynwhite · 2023-10-27T00:41:15Z

This is happening for me as well, and I ensured it isn't anything else by removing all extensions and reinstalling. Here is a complete log of what happened after my last window reload:

Can be temporarily fixed by rolling back the extension to v2023.10.40.

WitherZuo · 2023-10-27T02:19:56Z

me too, even if a simple python file...I use miniconda (Python 3.11.5, base environment).

For me, temporarily fixed by rolling back the extension to v2023.10.40 too.

Thanks all. We're able to repro this and are working on a fix.

Repro steps:

Create folder
python -m venv .venv
Add .egg file in .venv\lib\site-packages.
Add .pth file in .venv\lib\site-packages that points to the .egg.
Open folder in VS Code
Add empty .py file to kick off Pylance.
Crash

Here's a zip containing the .egg and .pth that I tested with. Change the path in the .pth file to match your test directory.

This issue has been fixed in prerelease version 2023.10.53, which we've just released. You can find the changelog here: CHANGELOG.md

darynwhite · 2023-10-27T21:08:29Z

This didn't seem to fix it for my system. Any steps I should take after installing the 2023.10.53 version?

debonte · 2023-10-27T21:13:34Z

@darynwhite, based on your log above it looks like you're hitting a different error. Is this still what you're seeing? If so, can you open a new issue? And provide some details on your setup so we can try to repro this ourselves? Do you hit this with notebooks or normal python files? Are you using a remote environment of some sort -- WSL, SSH, dev container, etc?

Just restating that this issue is fixed in our latest prerelease build -- 2023.10.53.

HenraL · 2023-11-02T13:29:41Z

How long does ir take for vscode to see the new version? Because currently, the latest version for them is v2023.10.50.

Edit: sorry, didn't see that we needed to switch to pre-release

debonte · 2023-11-02T13:35:33Z

Edit: sorry, didn't see that we needed to switch to pre-release

Here's a screenshot of that UI if others are having trouble finding it:

RisingLiberty · 2023-11-02T17:02:00Z

After using the pre-release version the language server errors out as soon as there's a change made to the file,
is this a known issue?

The line marked with a red arrow is a new line I've added

rchiodo · 2023-11-02T17:04:17Z

@RisingLiberty what's the error message that Pylance is giving?

RisingLiberty · 2023-11-02T17:12:38Z

It doesn't print anything to the console actually, the only thing I see at the end of a restart is the following
2023-11-02 17:06:35.630 [info] ERROR: The process "27076" not found.

there's also an error about a redundant open text document command for the file I'm editing, but I assume that's just warning?

after I've changed the file, notthing else gets emitted to the output console in vscode

rchiodo · 2023-11-02T17:19:49Z

hmm, Does hover over say 'print' work?

Like this:

The process 27076 not found shouldn't matter.

rchiodo · 2023-11-02T17:22:11Z

You might also try setting this:

"python.analysis.logLevel": "Trace"

RisingLiberty · 2023-11-02T17:27:58Z

yep, print works

not sure if it helps but the code above the changed lines still highlights as expected, it's only the new code and the lines below that gets messed up.

In there I've found a few references like this

wakusoftware · 2023-11-02T17:34:48Z

It updated to prerelease and it worked. Thanks

rchiodo · 2023-11-02T17:36:07Z

@RisingLiberty, No that shouldn't affect this. Your problem sounds similar to this: microsoft/pyright#6280

We should probably open a new issue to investigate. I believe the crash is fixed, otherwise hover on print wouldn't work.

RisingLiberty · 2023-11-02T17:40:25Z

Alright, no problem, thanks for the help, great stuff :)

kaern · 2023-11-02T21:02:07Z

Everything seems to work fine, but I am also getting some process error (this was not the case with .30):

That error doesn't matter. It's because we're killing a child process a lot sooner than we used to in 2023.10.30. We should just skip logging the error if it's not found.
