Pylance is not starting in certain projects. In these projects, the Pylance server does not start at all (see attached logs). As a result:

  • All pylance features are not working.
  • The Python Language Server option is missing from the Output panel.
  • Pylance-specific commands (e.g., Pylance: Start Logging) fail with command not found.

I have tried several troubleshooting steps, including:

  • Selecting the correct Python interpreter.
  • Creating new virtual environments.
  • Using a virtual environment from a working project.
  • Setting up a new project from scratch.
  • Using django-cookiecutter as a template.
  • Despite these efforts, Pylance still does not start.

I have several older projects where Pylance works as expected, indicating that the issue is project-specific rather than system-wide.

Environment data

  • Pylance version: 2025.2.101
  • Vscode Version: 1.97.2 (Universal)
  • OS and version: Osx 14.5
  • Python version (& distribution if applicable, e.g. Anaconda): Python3.13

Repro Steps

  1. Create a clean project.
  2. Create a virtual environment.
  3. Select the virtual environment as the Python interpreter.
  4. Install Django as a dependency.
  5. Create a test.py file and import django.models.
  6. Try using Go to Definition on the import.

We don't actually start the server ourselves. The core python extension is responsible for that. Transferring.

@bruecksen Try adding this to your user settings and reload. See if that addresses the issue.

@bruecksen Can you share the logs from Output > Python? I recommend setting the log level to Trace via Developer: set log level command from the command palette. Another thing you can do is run Python: Clear cache and reload

@tracerbiubiubiu Try adding the setting I mentioned in: #24852 (comment) and also try running Python: Clear cache and reload

hi,i have tried these ways below:

  1. uninstall python/pylance extensions and reload window
  2. add user settings as here:
    "python.analysis.logLevel": "Trace",
    "python.locator": "js",
    "python.experiments.optOutFrom": [
        "pythonTerminalEnvVarActivation"
    ],

and run Python: Clear cache and reload
and here is the result:

it seems there is no output in python language server
4. i tried reinstall VSCode and do all tries above again,nothing changes
5. i created a new project locally with all suggested configuration mentioned ,and even there is no python language server options in output. Only Python and Python Test Log, with python extension loading all the time

@karthiknadig I tried clear cache and setting the log level. Here is the Python output log. Now with the log level set to trace i see the pyenv error. I don't use pyenv. Is this something i can configure/disable?

@bruecksen the pyenv error should not affect the launch of pylance. Can you try this Help > Toggle Developer tools, then see if there are any errors reported there.

@github-actions github-actions bot added the info-needed Issue requires more information from poster label Mar 7, 2025

update,i delete all related to vscode,including config files and extensions ,all of them ,and reinstall it. Then pylance just works fine.Is there any further info i can provide ?
there is one thing i found
when i install Extension Pack for Java, the problem seems happened again, python extensions loading all the time, and uninstall packages in it and restart extensions , pylance works fine. Maybe try restart extensions will help.
