Actual behavior

Pressing Command + Shift + P, and then selecting the “Python: Select Interpreter” command

• Press Command + Shift + P
• Type in “python select”, then select the first result (“Python: Select Interpreter”)

I have tried uninstalling and reinstalling both VSCode Insiders, as well as the Python extension.

I saw this similar issue - https://github.com/DonJayamanne/pythonVSCode/issues/1394 - but reinstalling didn’t fix it in this instance, and no explanation was given on that issue of the underlying issue.

I am on windows machine, I upgraded to the latest version and this problem started to appear.

I uninstalled all other extensions except python and when I am pressing Ctrl + Shift + P, and then selecting the “Python: Select Interpreter” command

I get: Error command ‘python.setInterpreter’ not found

If people have issues with the automatic updating then please completely uninstall the Python extension, close VS Code, open it again, and then try installing the extension. If that doesn’t work then please open a new issue.
