This happens when I try installing pyinstaller (on MacOS Mojave) and searching I can't find anything on the error.
Strangely, if I try installing on my personal user account on the Mac (both are admin) it works.
Any suggestions?

while installing the collected packages. The install never completes; pip says it was never installed. I would greatly appreciate any help troubleshooting.
In the off chance anyone else has this problem, I found a temporary fix that will probably make python stop working in a few days.. I went to ln 1088-1090 of /usr/lib/python3.7/configparser.py and replaced that bit about raising an exception after an if statement with
while (self._strict and
(sectname, optname) in elements_added):
elements_added.pop()
This seemed to have fixed the problem, albeit not in the most pretty method, as installation pf build and use of sdist now works ok.

Any idea what could be the problem, or how to solve it?
Thanks for the help in advance!
I did not find any uniform solution to this problem. You can try the following troubleshooting steps. one of them should work.
Upgrade the pip version.
Change the library/package version.
If you are installing from source, try a different .whl package or use tar.gz.
Use --no-use-pep517 with your pip install command (didn't work for me though, but I see it worked for some).
I got the same error with a different library and --no-use-pep517 did not help. However this did:
python -m pip install --upgrade pip
I am unable to install youtube-dl-api-server. I am using Python 2.7.9. It looks like there is a bug in some dependency. I have tried install from source code but I was with the same result. After running command pip install –pre youtube_dl_server I got this message:

I am using Python 2.7.9 on Ununtu Server. Do you have any idea how to solve this?
Thanks metjuf
There is a strange character in your command, most likely the result of some automatic conversion. I'm talking about – (U+8211, b'\xe2\x80\x93' as UTF-8). So instead of
pip install –pre youtube_dl_server
run
pip install --pre youtube_dl_server
On a MBP, following instructions (http://techblog.rosedu.org/python-environment.html), I installed Xcode 4.4.1, brew (brew doctor says all set), and then python. Next, I tried to setup virtualenv:
> $MYPYTHON/bin/python distribute_setup.py
> $MYPYTHON/bin/easy_install pip
> $MYPYTHON/bin/pip install virtualenv
I then created a virtual environment and tried to install django:
> $MYPYTHON/bin/virtualenv $MYENV
> $MYENV/bin/pip install Django
It downloads 98% and then hangs for a while, and finally I get a traceback indicating a timeout:
pcm#pcm-mac[302]% $MYENV/bin/pip install django

I see the same thing, if I just run the version of pip from /usr/local/bin/. I tried other packages (selenium, mock) and they downloaded and installed fine.
I'm at a loss as to what I may be doing wrong, or if there is some issue with django installs via pip. Advice?
Use:
pip --default-timeout=60 install django
