Cartopy: Cannot install cartopy with pip on windows

[veenstrajelmer]

Description

I cannot install cartopy with pip, I see several solved issues reporting the same that are reportedly solved, but still it does not work for me. I would like to install it via pip, since then it is easy to set is as a requirement of my own package.

Code to reproduce

pip install cartopy

You do not have the required dependencies for cartopy installed. Cartopy requires two C++ libraries, geos (https://trac.osgeo.org/geos/) and proj (https://proj.org/), to be available. Unfortunately there happen to be two completely different packages in PyPI that use these same names (https://pypi.org/project/geos/ and https://pypi.org/project/proj/), which is what you have installed. The correct libraries cannot be installed with pip as far as I know.

I'm not a Windows user so I'm not exactly sure which is the best way to get you up and running from this point. Do you have any ideas @QuLogic?

[veenstrajelmer]

Thanks for your response. The same names indeed confused me, thanks for the clarification. I was aware that the dependencies were not installed, but I am used to pip solving this for me of course. It seems however that pip cannot reach the dependencies, which is inconvenient. Does this mean that I cannot install cartopy via pip at all? Then I will have to a conda install, since this does do the trick. This would however mean that I cannot include cartopy as requirement the setup.py of my own package.

You can also get binaries from Christoph Gohlke: https://www.lfd.uci.edu/~gohlke/pythonlibs/

There cannot be any binaries until we solve #805. Closing as a dupe of #1174.

hi.
i have gotten geos and proj library from OSGeo4W on windows. then, set PATHs of \bin(include dll) and \include (includes such as geos_c.h) . however, follow error happens:

> pip install cartopy

 trace.cpp
  lib/cartopy/trace.cpp(665): fatal error C1083: include ファイルを開けません。'geos_c.h':No such file or directory
  error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Community\\VC\\Tools\\MSVC\\14.26.28801\\bin\\HostX86\\x64\\cl.exe' failed with exit status 2
  ----------------------------------------
  ERROR: Failed building wheel for cartopy

how can i solve to set ?

[Xeozim]

@Cartman0 the solution to that is to specify the include and library directories when calling pip install. Assuming you've used the default OSGeo4W install directory, this would be:
pip install --global-option=build_ext --global-option="-IC:\OSGeo4W\include" --global-option="-LC:\OSGeo4W\lib" cartopy
Pip will then pass these options to MSVC. See this SO post

conda install -c conda-forge cartopy works well and solves the problem in my windows computer.
