There are problems playing the pysolfc solitaire game on the latest release of Linux Mint 21 (Vanessa).
The game requires the
formatter module from the Python
Standard Library, which had been deprecated since Python 3.4,
and has been removed in Python 3.10.
An easy, but ad-hoc workaround goes as follows:
Extract the required file to a directory of your choice:
tar -axOf Python-3.9.14.tgz Python-3.9.14/Lib/formatter.py > ~/lib/formatter.py
PYTHONPATHto include this directory. In t/csh:
setenv PYTHONPATH "$PYTHONPATH":~/lib
This assumes that
PYTHONPATH already exists;
setenv PYTHONPATH ~/lib.
The pysolfc team has a permanent solution in its latest release, but until that propagates to the distributions, the steps above provide an easy and relatively clean workaround.
