setup(name="loc", options=opts)

requirements.txt:

--extra-index-url https://archive.panda3d.org/
panda3d

pip version: 20.0.2
panda3d version: 1.10.5
wheel version: 0.34.2
I have windows 10 64 bit, with python 3.7 32 bit installed.
previously I didn’t have this problem and the game compiled fine.

This is a known issue, you should downgrade pip to <20:

python -m pip install -U 'pip<20'

thanks.
it has been fixed.
