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 over
ride this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.


I'm installing the necessary packages but I couldn't do it somehow. The python3-xyz package cannot be installed and I tried "pipx install xyz" and it doesn't install, what is it?

Just encountered this error. Looks like they are trying to prevent people from breaking python. Best practice is to use a virtual environment to install packages. To do this cd to the dir you would like to install your virtual environment I usually put it in the dir of the tool I am installing packages for. Next run

Code:

---

virtualenv -p {PYTHON  VERSION} {NAME OF VIRTUAL ENVIRONMENT}

---

. Next run

Code:

---

source  {NAME OF VIRTUAL ENVIRONMENT}/bin/activate

---

. After that you can proceed use pip. To exit the virtual environment simply run `deactivate`. Below is a quick command to copy and paste:

Code:

---

virtualenv -p python3 venv; source venv/bin/activate

---
