Cannot install cartopy

Question

I am using PyCharm IDE and am unable to install 'cartopy'.
When I run the command `pip install cartopy' in the PyCharm terminal I receive the following error message:

Do you have GEOS installed and what version? https://trac.osgeo.org/geos/ — Cody Glickman, Mar 21 '19 at 18:58
I have installed it on windows from https://proj4.org/install.html#install — Sagar Jogadia, Mar 21 '19 at 19:02
The installed GEOS does not seem to be connecting to cartopy with a pip install. You may have to install cartopy from source or use conda + conda-forge in PyCharm. You may want to try to put GEOS in your path manually then try a pip install https://stackoverflow.com/questions/9546324/adding-directory-to-path-environment-variable-in-windows — Cody Glickman, Mar 21 '19 at 19:22

Cartopy documentation recommends using Conda (link):

conda install -c conda-forge cartopy

Installing it using pip is also possible, but since Cartopy has a bunch of non-Python dependencies (like Proj and GEOS), you'll have to install those separately. That's a hassle and it's easy to end up with errors like the one above. Conda on the other hand can also take care of those non-Python dependencies for you.
