Pyright is using Incorrect Interpreter Path

Type: Bug

Behaviour

Expected vs. Actual

The python plugin sends the incorrect interpreter path to langauge server plugins such as pyright if the name of the virtual environment name begins with "python" (e.g. python_env) (as far as I can tell from trying many different names).

For some reason this only seems to affect the name of the virtualenv itself. If the virtualenv has a path such as /tmp/python_envs/venv/ then the plugin detects the interpreter path correctly.

Steps to reproduce:

1. create the following settings.json

{
    "python.languageServer": "None",
}

1. install the python and pyright plugins
2. create a virtual environment with a name beginning with python (e.g. python_env)
3. activate the virtual environment
4. open vscodium in an empty directory
5. create an open a .py file

The output of the python plugin:

The output of the pyright plugin:

[Info  - 21:30:31] Pyright language server 1.1.345 starting
[Info  - 21:30:31] Server root directory: file:///home/matthew/.vscode-oss/extensions/ms-pyright.pyright-1.1.345/dist

[Info  - 21:30:31] Unable to get Python version from interpreter

pyright is receiving the root directory of the virtualenv instead of the interpreter path.

A simple workaround is to rename the virtual environment but this is still a bug as the result is unexpected.

Diagnostic data
