Error Installing Python Libraries through Nexus Repo Manager

Question

I am currently trying to install two libraries.

Running: C:\Users\J39304\Desktop>python -m pip install pyinstaller yields me the following error:

I also noticed that running a similar command, C:\Users\J39304\Desktop>python -m pip install auto-py-to-exe, results in the exact same error.

However, when I ran C:\Users\J39304\Desktop>python -m pip install keras it installed just fine.

I have already made sure that I am using the latest version of pip by running python -m pip install --upgrade pip

I have not found any resources for this error.

Answer 1

raise X, Y is Python2-only syntax. Somehow you've managed to install a Python2-only library to Python3 site-packages. You need to cleanup site-packages and install newer versions of libraries.
