[XiaofeiQian]

I have same error on Windows 10, and find someting in [Extension Host]. Python interpreter find command:

"D:\\Programs\\Python\\venv\\rasa\\Scripts\\python.exe" "c:\\Users\\Miku\\.vscode\\extensions\\ms-python.python-2020.3.71659\\pythonFiles\\interpreterInfo.py" 

works in cmd and get:

{"versionInfo": [3, 7, 7, "final"], "sysPrefix": "D:\\Programs\\Python\\venv\\rasa", "version": "3.7.7 (tags/v3.7.7:d7c567b08f, Mar 10 2020, 10:41:24) [MSC v.1900 64 bit (AMD64)]", "is64Bit": true}

but it not work in pwsh(powershell 7.) or powershell(5.), it will return nothing.

If I set windows ComSpec to pwsh, and restart windows, when I open a python file by vscode it will get this Error "Python is not installed." and python: select interpreter shows nothing.

And I change ComSpec back to cmd, then restart windows, everything woks fine.

mybe we should use:

D:\\Programs\\Python\\venv\\rasa\\Scripts\\python.exe "c:\\Users\\Miku\\.vscode\\extensions\\ms-python.python-2020.3.71659\\pythonFiles\\interpreterInfo.py" 

Not Quote python.exe just the interpreterInfo.py file.
