AttributeError: Module Pip has no attribute ‘main’

I am trying to build the python api for an open source project called Zulip and I keep running into the same issue as indicated by the screenshot below.

I am running python3 and my pip version is 10.0.0. The file in question is setup.py and the code that is messing up is when the pip.main() attribute is accessed to install a package.

Now, I know this build should succeed because its an open source project, but I have been trying for hours to fix the dependency issue regarding pip.main().

Any help would be greatly appreciated.
