Errors when installing Basemap in Mac os

[yansinhuang]

I'm running these in my Mac' s terminal, with python 3.7.0.
It seems to be some problems with numpy or Cython but I pretty sure I have already installed them.
numpy 1.15.4
Cython 0.29.2
pyproj 1.9.5.1
geos 0.2.1
Above are some relative module that I already have.

Any idea or suggestions?

I know that I am coming super-late here, but there has been significant development on the basemap packaging in the last months. We are still missing precompiled binary wheels for MacOS, but it should be straightforward to install from the source distribution available in PyPI:

1. First, you need to have an appropriate installation of GEOS (e.g. through HomeBrew) and a C compiler.
2. Then, set the environment variable GEOS_DIR to the installation folder (i.e. the geos_c.h header should be found in ${GEOS_DIR}/include).
3. Finally, install basemap with pip normally: python -m pip install basemap
4. Optionally, if you need the high-resolution datasets: python -m pip install basemap-data-hires

Feel free to try out and report any issues from following the former steps.

I am closing the issue, because with the upcoming release 1.4.0 (in a couple of days) I will be uploading MacOS wheels to PyPI manually, and since release 1.3.9 we already have MacOS arm64 packages in the conda-forge channel, so hopefully these installation issues on MacOS will become less common.

Feel free to reopen the issue if any of the problems persists.
