Cannot install Jupyter for python 2.7 due to setuptools not being the right version - python-2.7

Question

I am developing a plugin that must be developed in Python 2.7, not Python 3, due to the application it is for requiring it. I recently upgraded to PyCharm Professional and was hoping to use the built in Jupyter support for some testing. However it says "Jupyter is not installed." I have used Jupyter Notebook for Python 2.7 before, but had to start the server from Python 3 and then launch a kernel using Python 2.7 (which was a nightmare in itself due to the accent in my name.) When trying to install Jupyter in my Python 2.7 interpreter (using "pip install jupyter"), it complains that there was "No matching distribution found for setuptools~=53.0.0". On some googling and testing, I have found that in Python 2.7 setuptools cannot be updated beyond 44.1.1.
One thing that I REALLY hope is not relevant but has been the bane of my Python 2.7 coding life so I will mention it: My user folder has an accent in it due to the fact that my name is Réka. I have done everything in my power to route things to the C:\ folder instead, but it persists in looking at things in my user folder, which sometimes causes issues.
I think it is also complaining about a package called "maturin" but I am having trouble parsing the error. If anyone would like to look, here is the full error text (with my username removed):

I would like to know if there is an earlier version of Jupyter or something that is compatible with setuptools 44.1.1 that I could install - maybe I'm not googling the right things, but I haven't been able to find one. I can use my Python 2.7 kernel so it's not a blocking issue, but it would be very nice to be able to use Jupyter directly from PyCharm instead.
