I tried to install it via "pipx install -e .[develop]". It's
pyproject.toml has a bug: A missing dependency "dateutil". But
"dateutil" is not available from PyPi for Python 3.11 (the default
in Debian 12). But thanks to great Debian they have a
"python3-dateutil" package. I installed it.
This can be installed via pip:
I'm aware of this. But this is not the question.
I would like to know and understand why my via "pipx" installed package
"hyperorg" is not able to see the systems packages installed via "apt
install python3-dateutils"?
Is this the usual behavior? Is this correct?
Yes. By default, the virtualenv contains just what you've installed.
It's designed to give you tight control over what's installed, so you
can track dependencies, avoid accidental inclusions, etc. As usual, you
don't have to accept the default. For example, for the venv module:
usage: venv [-h] [--system-site-packages] [--symlinks | --copies] [--clear]
[--upgrade] [--without-pip] [--prompt PROMPT] [--upgrade-deps]
ENV_DIR [ENV_DIR ...]
Creates virtual Python environments in one or more target directories.
positional arguments:
ENV_DIR A directory to create the environment in.
options:
-h, --help show this help message and exit
--system-site-packages
Give the virtual environment access to the system
site-packages dir.
