Missing Python Module. How to install?

Platform Development
#1

RPNCALC stopped working at V3.3

Starting it from the commandline I get a python error:

ModuleNotFoundError: No module named ‘mpmath’

I am guessing the module was removed from the distribution.

I try installing it:

[nemo@Sailfish ~]$ python3 -m pip install mpmath
/usr/bin/python3: No module named pip

and no PIP

[nemo@Sailfish ~]$ harbour-rpncalc

Hi,
try
devel-su pkcon install python3-pip

and then
pip install --user mpmath

That should do it.

Thanks, that was all that was wrong, and I have a calculator again.

Next question will be how to add what is needed to the RPNCALC rpm, but that will have to wait until I can get the development env going on my machine again.
