Failing to install PyPi package gdown via py2dsp
On Debian-like/apt-based distributions, instead of installing Python packaged system-wide with pip install --system, we use APT packages. Here:
Install a Python package on Debian/Devuan when apt has no package for it
is a discussion on how to do that. Unfortunately, this fails when I try it with the gdown package:
# mkdir /tmp/gdown
# cd /tmp/gdown
# py2dsp --build gdown
W: py2dsp cache:67: cannot load cache (_load_package_names:():{}): unpackb() got an
unexpected keyword argument 'encoding'
E: py2dsp py2dsp:172: 'build-system'
is this a py2dsp bug? A problem with my own system somehow?
This is a known bug in py2dsp, unfortunately with no fix for now.
Pointing py2dsp at the source repository doesn’t work either, so I suspect the only way forward is to write a source package from scratch using the source code. To get started:
$ curl -Lo gdown-4.7.1.tar.gz https://github.com/wkentaro/gdown/archive/refs/tags/v4.7.1.tar.gz
$ tar xf gdown-4.7.1.tar.gz
$ cd gdown-4.7.1
$ debmake
(using the debmake package).
