			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.

			If you wish to install a non-Debian packaged Python application,
			it may be easiest to use pipx install xyz, which will manage a
			virtual environment for you. Make sure you have pipx installed.

			See /usr/share/doc/python3.11/README.venv for more information.

			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.
			</pre>
			please try to fix it according to following steps:
			* You can use Python's venv like described here. [ https://stackoverflow.com/a/75696359/10626495 ] <br>
			However if you really want to install packages that way, then there are a couple of solutions:
			* use pip's argument --break-system-packages,
			* add following lines to ~/.config/pip/pip.conf:
			<pre>
			[global]
			break-system-packages = true
			</pre>
			and then execute "sudo -H pip3 install -e ." again. <br>
