Proj version 0.0.0 is installed, but cartopy requires at least version 8.0.0.

[AndreasLuckert]

Description

The shell command pip install cartopy led to several errors, again related to proj, this time on Windows 10.
I'd already filed another issue, which happened on Lubuntu due to some other reasons.

This time on Windows 10, I tried to install all the necessary dependencies respecting the official cartopy docs, with as always proj being the most complicated one:

1. I went to osgeo4w - download repo,
2. downloaded the osgeo4w-setup-x86_64-v1.exe,
3. followed the proj - install instructions (see attached screenshot as installation proof),
4. and tested it in the osgeo4w - Shell (see attached screenshot).

Yet, the cartopy is warning me consistently that Proj version 0.0.0 is installed, but cartopy requires at least version 8.0.0.

More details in the entire error traceback below.

Code to reproduce

pip install cartopy

Traceback

From pip install cartopy 2> error_log_install_cartopy.txt I obtained:
