I hade the same problem but i could solve it with some good old reading

https://www.raspberrypi.com/documentation/computers/os.html#python-on-raspberry-pi

I used the per-user enviroment

Use the following command to create a virtual environment in a hidden folder in the current user’s home directory:

python -m venv ~/.env

Run the following command from any directory to start using the virtual environment:

source ~/.env/bin/activate

You should then see a prompt similar to the following:
(.env) $:

To leave the virtual environment, run the following command from any directory:

deactivate

When you are inside your virtual environment you can install mmpm an can also use the whole commands like mmpm version ect.

Hope this helps
