Package: python3-pip Version: 23.0+dfsg-1 Severity: important X-Debbugs-Cc: [email protected]
Hi! I just updated python3-pip and was greeted with a NEWS message about PEP 668 support: This version of pip introduces PEP 668 support. Debian's python3.11 interpreter will soon (>= 3.11.1-3) declare the installation to be EXTERNALLY-MANAGED, instructing pip to disallow package installation outside virtualenvs. See: https://peps.python.org/pep-0668/ Practically, this means that you can't use pip to install packages outside a virtualenv, on a Debian system, any more. See /usr/share/doc/python3.11/README.venv for more details. If that isn't available yet, check: https://salsa.debian.org/cpython-team/python3/-/blob/master/debian/README.venv Not being able to install packages system-wide seems like a good idea, I fully support that. But I often install the Python packages I'm developing under my own user account with "pip install -e", which is also made impossible by this change. And I intentionally do not use virtualenvs for this because I want to have all dependencies provided by Debian packages, not downloaded from PyPI. And as far as I can tell there is not even an option I can give to pip to tell it to allow me to install to ~/.local anyway. PEP 668 mentions a --break-system-packages (as an example), but such an option doesn't seem to actually exist. - FC
