Hi! I have been trying to install Geomeppy (0.4.8) for Windows. As I understand, this requires Numpy (1.14.0), Shapely (1.6.4), and Matplotlib (2.1.2). Except for Shapely, I have the rest installed. Since Shapely needs GEOS, I have that installed as well. However, Shapely installation throws an error still. I cannot make much of the error, any help will be much appreciated. Thanks!

Error Message! Collecting shapely   Using cached Shapely-1.6.4.post1.tar.gz
    Complete output from command python egg_info:

The problem is you're missing the "geos_c.dll". I don't know how you're installing shapely, but this error can occur if you do pip install shapely on Windows since Windows doesn't build the Geos dll.

Try using either the Windows installer from Shapely here, or from Christophe Gohlke here.

Thanks Jamie! Geomeppy is working now! I guess you are right about the installation command! This link is helpful for python newbies for selecting appropriate whl files installing using whl files.

@Jamie Bull it looks like @Nimafo is having a similar issue trying to use geomeppy on Windows, they have started a new post here.
