versioneer installed, but pip install still gives ModuleNotFoundError

I have the versioneer module installed in my environment, as confirmed by running python -m versioneer --version. Yet when I pip install cartopy, I still get a ModuleNotFoundError, as shown below:

(GIS3) gholl@lce00:~> python -m versioneer --version

How can it be that the versioneer module is installed but pip install cartopy still fails to find it?

(I'm aware I should probably not pip install into a conda environment, but I am meanwhile debugging a problem where a complete conda install either wants to downgrade Python, or results in undefined symbol or cannot open shared object file errors, so this question does have an XY problem aspect to it — however, I still have additional things to try for my Y)

I ran into this error, and this solved it for me.

I think versioneer needs to be installed in the build environment, which I have to assume is separate from when you've installed it.

There's a known issue with Cartopy 0.17.0, as referenced here: Unable to install cartopy from pip on MacOSX #1270

You can try pip install cartopy==0.16.0 instead, or also try using pip install --no-use-pep517 cartopy. Alternatively, this seems to be an issue with >= 0.19, so you can also try downgrading pip.
