py --version shows 3.10 which was installed manually in Windows, not from cmd

Pip install attempts to run with 3.9, then throws the error:

no "\\python39\\python.exe" nor "Scripts\\pip.exe"

How do I prioritise running with new version ?

Tried

  • Deleted path env. variables and 3.9 launcher, didn't solve.

  • up to date: pip setuptools wheel,

  • forced pip installs

  • What does your path look like now (make sure you check in a new terminal window)? What do you mean by "deleted 3.9 launcher"? If you're talking about `py.exe` then a) that should have been in a Windows system folder that you shouldn't modify manually and b) it is, by design, not version-specific. Does `py -m pip` work? – Karl Knechtel Apr 01 '22 at 07:31
  • Please take a look on [What is the reason for "X is not recognized as an internal or external command, operable program or batch file"?](https://stackoverflow.com/a/41461002/3074564) It describes fully the `Path` management on Windows. Please read also the Microsoft documentation page [FAQ's about using Python on Windows](https://learn.microsoft.com/en-us/windows/python/faqs) with information about `py.exe` and the Python documentation [Using Python on Windows](https://docs.python.org/3/using/windows.html). – Mofi Apr 01 '22 at 07:57

Have you rebooted your system after modifying the environment variables? Some applications only detect changes after a full system reboot.

You may need to do the following:

  • Restart computer / environment
  • Check start folder to see if you have Python there still
  • Run python3.9 in CMD to see if an exe is still in PATH

A quick fix would be to use:

pip3.10 install # package here
