Cannot install dependencies for QPageViewer alongside PyQt5

Question

I am trying to make a program with PyQt5 where on one side it displays a scrollable pdf.

I found a third-party tool called QPageViewer that is compatible with PyQt5, but it has python-poppler-qt5 as a dependency.

Every time I attempt to pip install python-poppler-qt5, I get the following error(s):

(.venv) PS Z:\Projects\PDF Scraping> pip install python-poppler-qt5

  note: This error originates from a subprocess, and is likely not a problem with pip.

× Encountered error while generating package metadata.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

I tried some other things that I found online such as:

• attempting to pip install python-poppler
• or python-qt5 (which broke my installation of pyqt5 altogether)
• upgrading pip
• upgrading sip
• switching between python versions 3.10 and 3.9

I even attempted to go a completely different route with PySide but I got the same exact error messages attempting to install that also.

I am at a complete loss and have been trying to fix this for over three hours with no breakthroughs. I appreciate any help that anyone has to offer.
