Currently discoverable Pythons: 3.11, 3.10, 3.9, 3.8, 3.7
Inspired by excellently written
Relieving
your Python packaging pain, this ~120 line shell script does one thing: let
you use and only use Pythons installed through system package manager, and
create virtualenvs using their venv.
Its name is a mix of puns: Max Payne is the painkiller addicted protagonist of the Max Payne series (don’t addict yourself to them, obviously); the inspiration is said to relieving pain, so it’s minimum pain; and, obviously, a python reference. It’s therefore pronounced like Min Payne or min pain, not min pine.
This script is supposed to be installed through the same package manager that installs Pythons for you. But since it’s barely created and known by no package maintainer, clone this repo instead. Then alias it. For example,
$ git clone https://github.com/bnoctis/minpyne ~/.local/share/minpyne $ alias minpyne=$HOME/.local/share/minpyne/minpyne.sh $ alias python='minpyne python' $ alias pip='minpyne pip'
The latter two aliases are optional.
The script has a pretty self-explanatory help message, by running it without
arguments or reading show_help() at its top. But if you want a quick intro:
$ sudo apt install python3.11 python3.11-venv # Debian, etc. $ sudo dnf install python3.11 # Fedora, etc.
Right, minpyne doesn’t install Python itself. That’s on your system’s package
manager. Make sure they provide a Python executable named pythonX.Y where X.Y
is its version, like 3.11. If not so, or you really really want to use a
custom Python, read on.
$ cd path/to/work $ minpyne local 3.11 $ minpyne local Python 3.11.2 /home/i/test/bin/python (virtualenv, links to /usr/bin/python3.11) # or $ minpyne local /path/to/custom/python
Under the hood, it calls /path/to/python -m venv .venv to create a
virtualenv. Nothing fancy. From now on, don’t use anything fancy to "manage"
this directory. rm -r .venv and reinstall dependencies if you must do so.
python or pip# with alias, just $ python -V # without alias $ minpyne pip install -U pip
$ minpyne local 3.12 $ pip install .
pyproject.toml is the new standard, you just need a pip install . to
install dependencies specified in it. How convenient.
