Actual behaviour

Go to definition doesn't work. I see infinity loader

Steps to reproduce:

1. Install python from pyenv (pyenv install 3.5.5 && pyenv shell 3.5.5)
2. Generate simple Django project, create env: python -mvenv env && source env/bin/activate
3. Try to create forms / models / views etc
4. From views or forms import model
5. Try to remove any py file from project:

[Error - 2:38:04 AM] One or more errors occurred. (failed to parse file file:///Users/ali/Projects/aliev/infinity-server/topic/views.py)

after that go to definition stops working

Hmm I think I know now when it's happening. When I removing some file from the project I get an error in console and goto definition stops working.

[Error - 2:14:59 AM] One or more errors occurred. (failed to parse file file:///Users/ali/Projects/aliev/infinity-server/topic/forms.py)

Same here, whenever I hit F12 the infinity loader spins forever and I have to reload VS Code.

VS Code Version: 1.30.2 (user setup)

EDIT: I noticed that the F2 key (Rename Symbol) does not work, either. Still seeing the infinity loader spin forever.

@aliev Version 0.1.75 of the language server was released yesterday. Could you do the following and update the language server to see if it solves your problem?

1. Run "Open Extensions Folder"
2. Quit VS Code
3. Open the folder for the extension (e.g. ms-python.python-*)
4. Delete the languageServer0.1.72 folder
5. Open VS Code
6. Open a Python file (I'm assuming you have "python.jediEnabled": false set)

That should lead to version 0.1.75 being installed.

[aliev]

@brettcannon seems to work for me! I have this output in console (the same steps but after removing and updating languageServer0.1.72):

@aliev glad that resolved it! Closing the issue.

[thewingit]

I've updated the language server which now is at v0.1.75.0, but the problem is still there on my side.. I will try to investigate further, if I think this is not a config issue on my side I will open another thread.

EDIT: Something magic happend: I debugged into my code, and after the debbuger was launched, F12 started working again!

Sometimes magic happens. Thank you for the support.
