thanks a lot, it was the only way thats work for me, to resolve the problem KeyError 'PROJ_LIB' martinchristen/EuroSciPy2018#2

I was so happy when I read this and knew I'd finally be able to get basemap to work!!

This gist was created quite a long time ago.

I recommend using anaconda in order to install basemap properly.

Or even better, you should consider switching to cartopy, which is more powerful than basemap. It can also be easily installed using anaconda.

Yeah, I agree, switch cartopy which same functionality.

I used anaconda; it works ok on the local machine; however, it gives different frustrating errors on the CI. I am considering switching to cartopy.
