How to install / update if setup.py does not exist?

[spyball4]

Since I run a Windows machine, 5.17 used to work in VMWare Debian about a month ago. Now with 5.19(?), I can pull the new code but upon any download, it gets stuck retrying downloads for all pages. This happened both before and after I did a git pull origin master. Worth pointing out is that without a setup.py, I cannot update the CLI like before. pip gives me a warning if I try to install it that way. What course of action is best here?

Try run command "pip install ." at the project directory
