 Wie behebe ich „Fehler: extern verwaltete Umgebung“ jedes Mal, wenn ich Pip 3 verwende?

Post by Guest »

Wenn ich pip install xyz auf einem Linux-Computer ausführe (unter Verwendung von Debian oder Ubuntu oder einer abgeleiteten Linux-Distribution), erhalte ich diese Fehlermeldung:

< pre class="lang-none Prettyprint-override">

Code: Select all

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.
Was bedeutet dieser Fehler? Wie vermeide ich es? Warum funktioniert pip install xyz nicht wie vor dem Upgrade meines Systems mit sudo apt upgrade?
