Installation on Linux mint

[wilson-2015]

Hi!

I have a problem installing crpropa on Linux mint version 19. I have installed from git using system path procedures and I have followed the instructions perfectly well.

I have installed all the necessary packages including swig version 3.0.12. All the tests also ran successfully after installation.

However, crpropa doesn't run when I import it and it gives this error:
"""ModuleNotFoundError: No module named 'crpropa' """

Is there anything that I have left out? Below is a preview of the output when I run cmake::

From your output I see is that you use anaconda python next to the system python. Please make sure that the site package directory you are installing CRPropa into (/home/wilson/.local/lib/python3.7/site-packages) is used by your anaconda python installation as module search path.

Hi Tobias! Basically this is the problem I have been facing. I have been trying to make anaconda aware of the directory where crpropa is installed but it is not working, which is strange.

[TobiasWinchen]

Please note that our documentation so far does not cover the anaconda python case, and I have not used anaconda myself so far. Where does anaconda python put packages that are installed via pip / setuptools? From the CMake output I would guess that this is somewhere under /home/wilson/anaconda3 - possibly it makes sense to also install CRpropa under the anaconda directory using it as install prefix? Consider making a backup of the anaconda directory before trying this in case this damages the setup. You should probably check with the anaconda documentation on how to add 3rd party software to anaconda correctly.

Hi Tobias! Installing crpropa under anaconda has worked now running thank you very much.
