2 years ago Hi @SongJaeIn! It looks like the problem is coming from the current build dependency definition in the pyproject.toml, because it is pinning to a very specific numpy version (v1.16.6 for Python 3.9), and your computer fails to build this numpy version from source. I think https://github.com/numpy/numpy/issues/17987 is the issue that you are seeing on MacOS, which was not solved until numpy v1.21.0.
Your installed numpy library is newer (v1.23.1), which is perfectly normal. The original reason for being so specific with the numpy version for building is that we need to compile the distributed precompiled binary wheels with a very old numpy version to ensure that they work in as many computers as possible. For example, if the distributed wheels were compiled with numpy v1.23.1, later a user with numpy v1.19.5 would not be able to use them, but building basemap with an old numpy and later using basemap with a newer numpy does work. However, the combination of the former numpy bug on MacOS and the numpy pinning in the pyproject.toml is making you impossible to install basemap.
Probably the implementation in pyproject.toml is at the moment too overkilling, and it could be enough to replace the numpy requirements so that they use >= instead of ==. Anyhow in the GitHub workflows I install old numpy libraries on purpose before building basemap, so the workflows would not suffer with the change from == to >=.

But when I tried in Anaconda (Spyder)
from mpl_toolkits import basemap

Hi, I tried to install Basemap via pip in Mac OS, but I have encountered an error. I also tried with another version (1.3.0), but those resulted in another error related to GEOS (it is installed and the environment variable is set correctly though).
Really appreciate your effort on this outstanding tool and thank you in advance for your support.
following is the log for installation of v 1.3.3:
