david@raspberrypi:~ $ python3 -m pip install --upgrade mmpm
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.

If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

@rohredd yes, python has taken to using a virtual env to enable loading different libraries for different apps on the same system

i am not a python programmer, so i dont know how to fix this, maybe google can help
“create python virtual environment”

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

@r0t yes, AND you need to activate the virtual environment you installed stuff in, before you use it…

like in scripts started by pm2
