If you can not locate epsg file at all, you can download it here:

https://raw.githubusercontent.com/matplotlib/basemap/master/lib/mpl_toolkits/basemap/data/epsg

And copy this file to your PATH, e.g. to:

os.environ['PROJ_LIB'] = 'C:\Users\username\Anaconda3\pkgs\basemap-1.2.0-py37h4e5d7af_0\Lib\site-packages\mpl_toolkits\basemap\data\'

This is the ONLY solution that worked for me on Windows 10 / Anaconda 3.
