What python version are you using? Is it explicitly compatible with the module you want to install? — Daraan, Oct 12 '22 at 12:54
python v 3.10.8, yes it is compatible. https://scitools.org.uk/cartopy/docs/latest/installing.html — Vijay Tiwari, Oct 12 '22 at 13:01
Did you install the required dependencies first as listed on the page you linked? These are essential for cartopy — Callum Rollo, Oct 12 '22 at 13:29
Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. — Community, Oct 12 '22 at 20:51
pip is terrible at managing non-python dependencies, including GDAL, especially on windows. you'll need to use pipwin or conda. see e.g. this question about the same issue when installing geopandas: https://stackoverflow.com/questions/54734667/error-installing-geopandas-a-gdal-api-version-must-be-specified-in-anaconda — Michael Delgado, Oct 13 '22 at 03:13

The root cause here appears to be an incompatible numpy version or broken numpy installation. From your error message:

ImportError: NumPy 1.10+ is required to install cartopy.

You have numpy fixed at too low a version in this environment. I can't say what exactly is holding you to this version of numpy, but you should be able to get around it by building a new environment with e.g. virtualenv, activating it, installing numpy > 1.18 (as per cartopy requirements) then installing cartopy.
