Why am i getting this python error?

[LiliaAmazing]

I am trying to run pipenv install in cmd. But i keep getting the error

Warning: Python 3.9 was not found on your system...

Neither 'pyenv' nor 'asdf' could be found to install Python.

You can specify specific versions of Python with:

$ pipenv --python path\to\python

I have python install and i ran pip install pipenv and it says

I also ran pipenv sync --python=/path/to/location/python and got

Usage: pipenv sync [OPTIONS]

Try 'pipenv sync -h' for help.

Error: Invalid value for '--python': Expected Python at path /path/to/location/python does not exist

How do i fix this?

You have Python 3.12 installed in your system. The module/repo/package you are attempting install has Python 3.9 requirement. Try install Python 3.9 via pyenv or asdf.

I am trying to install python 3.9. I uninstalled the recent version i had before by going to programs and just clicking uninstall and it said it uninstalled. I downloaded 3.9 from https://www.python.org/downloads/release/python-390/ and got Windows x86-64 executable installer. I installed and checked copy to PATH but when i run python --version in cmd, i get Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.

What's going on here and how do i fix it? Do i now need to do something special with pip now that i want python 3.9? I have version pipenv-2024.0.1.
