You'll want to remove it via apt first (if for some reason it is actually installed). Then use pip/pip3 Maybe they forgot to add it or figured it was better to use the often more up to date pip version.

Re: Zero 2W won't boost flashed os

As a above, check that that OS is said to be compatible with the Zero2 There is a small file a Pi reads at boot up to know how to run on that Pi. (mentioned as firmware above). If the Zero2 file is not there then it does not know what to do. It is best to check with the maker of the OS. For example ...

Re: Raspberry Pi Zero W Test Pad Locations

The only extra pads are the (it think) smaller wifi/bt ones up near the gpio pin, just above the WiFi chip.

The rest are the same as the PiZero 1.3, with a slight movement on the USB pins by a fraction.

Which pins are you wanting?

Or is it the dimensions you're looking for?

This looks to be another option.
Geopy and suntime python modules.

One thing you might need if you don't have an internet connection is to have some way of keeping the time.

You could use a GNSS/GPS device to get the time and an accurate location.
Or a real-time clock (RTC)

You don't often need that for WiFi, but then connect a phone (or the Pi hooked up to the TV via HDMI) to log in for internet access.
