[pyngl-talk] A problem on installing PyNIO

[Kevin Hallock]

Hi Zhengyu,

There are still some compatibility issues with dependency packages when using the command “conda create -n pynio_pyngl -c conda-forge pynio pyngl” to install PyNIO and PyNGL.

However, we’ve found a workaround that should allow you to install and run both PyNIO and PyNGL:
conda create -n pynio_pyngl -c conda-forge pynio pyngl poppler=0.52 xerces-c=3.1

Hopefully being this verbose will not be necessary in the future, but unfortunately this is the simplest solution available for installing PyNIO/PyNGL using conda at this time.

Please let us know if you encounter any further unexpected behavior.

Thanks,
Kevin

I really need your help,  my system version is “Linux localhost.localdomain 3.10.0-514.26.1.el7.x86_64 #1 SMP Thu Jun 29 16:05:25 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux”, I have printed the “conda list”,  you can see  see attached for details .
