Describe the bug / provide steps to reproduce it

Pyright complaints about unresolvable imports and undefined values.

Fresh install of Zed and starting a python project with virtualenv pyright highlights all non-standard library imports as unresolvable. This is fine because pyright doesn't know anything about my virtualenv. But it also marks any python standard functions, e. g. print() or int().

(1) Using ./pyproject.toml it recognizes all custom imports but no longer standard library. Still does not know anything about standard python functions.

[tool.pyright]
venvPath = "."
venv = ".venv"

(2) Using ./pyrightconfig.json same results as with ./pyproject.toml.

{
  "venvPath": ".",
  "venv": ".venv"
}

(3) Using global ~/.config/zed/settings.json it does find all third-party libraries installed inside .venv and also finds standard libraries. But it still does not know about standard functions (print, int, dict, sorted, ...).

{
  "lsp": {
    "pyright": {
      "settings": {
        "python": {
          "pythonPath": ".venv/bin/python"
        }
      }
    }
  }
}

I'm quite sure that some weeks ago I could solve all pyright errors by using pyproject.toml or pyrightconfig.json. But in the meantime nothing seems to work anymore. Using combinations of those 3 options above pyrightconfig.json will overwrite pyconfig.toml and settings.json in their behaviour.

Environment

Zed: v0.146.4 (Zed) OS: macOS 13.6.7 Memory: 8 GiB Architecture: x86_64

Python is installed via brew (python@3.12). PyRight is not installed via brew or as global pip package. (Brew stops one with a warning when trying python3 -m pip install <package> outside of an virtualenv.)

Hey @timptner, do you have any projects you could share that show the issue? I'm not able to reproduce this on my end - here's a project where print is being recognized by pyright:

We've had some issues where restarting Zed, after creating a pyrightconfig.json file, would correct some weird pyright issues - do your issues still persist after restarting Zed?

[timptner]

Freshly project:

Restartet Zed multiple times in between those 3 options above. Even restarted Zed before creating this project and also tried zed . while CWD is this project, which some other issue mentioned as solution.

I noticed that each time I restart Zed it always checks for pyright updates and everytime downloads pyright. Don't know if this is expected behaviour.

[timptner]

Just checked with my second workstation (debian) and there I don't get the pyright errors

I've encountered the same problem:

1. Open empty directory
2. uv init
3. uv venv
4. Set pyproject.toml dependencies to dependencies = ["requests"]
5. uv pip compile pyproject.toml -o requirements.txt
6. uv pip sync requirements.txt
7. Add import requests to src/project/__init__.py

There will be a warning with Pyright: Import "requests" could not be resolved from source.

As @timptner said, this can be resolved by adding the following to pyproject.toml:

[tool.pyright]
venvPath = "."
venv = ".venv"

However this is a tweak that isn't needed when working in other editors.

@JosephTLyons the same behaviour, venv's libraries pyright recognizing correctly, but pythons builtins not:

Pyright: "str" is not defined (reportUndefinedVariable)
Pyright: "print" is not defined (reportUndefinedVariable)
Pyright: "range" is not defined (reportUndefinedVariable)

Previously it worked fluently, it seems that something became wrong after auto-update

I using the same setting for venv and I tried recreate venv and restart zed. Disable of venv settings also not working.

[timptner]

Just installed pyright with pip and checked the files.

(.venv) aiven@MacBook-Pro test % pyright --version
pyright 1.1.375
(.venv) aiven@MacBook-Pro test % pyright main.py
0 errors, 0 warnings, 0 informations

Seems like it's a local problem of the pyright version inside Zed.

[ikheifets]

@timptner for me working this workaround:

rm -rf ~/Library/Application\ Support/Zed/languages/pyright/

After that need to restart Zed and it will automatically download latest pyright version

This has solved it!

[imbev]

This is still a problem on the Linux version of Zed.

After running this command, the newly downloaded pyright has the same issues.

rm -rdf ~/.local/share/zed/languages/pyright/

[ikheifets]

@imbev you have another problem. In our case pyright can't recognize python stdlib (it seems that we've got broken version of pyright), in your case third-patry libs from venv, big chance that you wrongly configured virtualenv, just read docs.
