Trying to modernize an old Django project (2.2), and its requirements.txt (generated via pip freeze) has some lines that make pip install throw fits:
distro-info===0.18ubuntu0.18.04.1
I interpreted the errors I got for the first one (see the error output in its entirety at the bottom) as the version string not conforming to PEP-518, but it doesn't even mention the === operator. This SO thread, What are triple equal signs and ubuntu2 in Python pip freeze?, has a similar issue, but:
The errors they got is different (ValueError as opposed to my ParseError).
The solution was to upgrade pip, but I'm already using the latest one.
Now, pip install distro-info works so should I just go with that?
update: The project I'm trying to update has been conceived around 2020, and according to the PyPI history of distro-info, it had a 0.10 release in 2013 and a 1.0 in 2021. Could this anything have to do with the weird pip freeze output? (From this PyPI support issue.)
The error:

Looks like your library was discontinued. In PyPi, infact, I can see there are only 1.0 and 0.10. If you need that specific version, then you need to setup a manual installation, downloading the source here. Either, you can upgrade your version and try to refactor any possible problem coming after!
In case, if you need to dockerize your app, setting up a script for the manual installation of a library is simple.

This has always been a relatively straightforward process, so I'm hoping that it's just a simple oversight. Thanks in advance!
I ended up installing a slightly older version of miniconda2, which I was able to find in the anaconda archives. The build completed successfully after that.
I don't understand the syntax to call the render feature of ERAlchemy (https://pypi.org/project/ERAlchemy see "Usage for Python"). I am using Python 2.7, sqlite3, and PyCharm. I have ERAlchemy, GraphViz, and PyGraphViz installed.
I am trying the following, but it cannot connect to the database:

Ah! Found the answer here

I've reinstalled everything at least twice, updated, tried sudo -H, but nothing seems to work. It seems like a problem with setuptools, but I have no idea how to fix it.
Mac OSX 10.11.6 (El Capitan)
Python 2.7.13
Pip 9.0.1
After carefully reading through the error message, I managed to find the file called ffi_build.py under the Python folder I was trying to bind. As stated in the error message, at line 34 there was a module naming statement that contained a '/'. By replacing that '/' with a '.' I solved the issue and managed to bind the Python wrapper with no issue whatsoever.
