No module named 'pycmsg' #22

Open MartianColonist opened 3 hours ago

After installing MSG-1.3 on Ubuntu 20.04 in a fresh conda environment, I'm hitting the following error upon importing pymsg:

Traceback (most recent call last): import pymsg as pymsg File "/home/....../anaconda3/envs/....../lib/python3.11/site-packages/pymsg/init.py", line 29, in import pycmsg as pyc ModuleNotFoundError: No module named 'pycmsg'

Is there any additional step, beyond those in the installation instructions in the MSG documentation, to install the pycmsg submodule?

It looks like to solve this problem the user needs 'cython' to be installed in their conda environment before compiling MSG ('make -j -C $MSG_DIR').

Can you add a note on the installation page under 'Building MSG' noting that cython is a prerequisite for pymsg?
