Struggling to install pyobject-1.0

Question

I have developed some python code on Windows 3.9.0 environment. I run pip freeze prog.py > requirements.txt. I then tried to re-create a similar environment on my RaspberryPi running Python v3.7.3.
However, sudo pip install -r requirements.txt is always failing to install the pyobject.

I manually tried to explicitly install this specific module, but it is continually failing.

pi@raspberrypi:~/operational_report $ sudo pip install pyobject
