Hi, @unbeatable-101! I have never seen this kind of error when installing basemap from its sdist, does the following link help? Maybe you have PIP_TARGET defined on your environment: https://stackoverflow.com/questions/72297487/pip-install-error-cannot-set-home-and-prefix-together

The issue turned out to be this in pip.conf

[global]
target = /opt/homebrew/lib/python3.10/site-packages/

after commenting out it built

Great to hear! I am closing the issue then.
