pip._vendor.pep517.wrappers.BackendUnavailable error while installing cryptography

I'm trying to install cryptography to my system, but I get this error:

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

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?

Issues installing python package Six (to install Pip)

We recently uninstalled pip to do some cleanup on Mac OS X El Capitan. Now trying to re-install pip.

Python 2.7.9+ and 3.4+
Good news! Python 3.4 (released March 2014) and Python 2.7.9 (released December 2014) ship with Pip. This is the best feature of any Python release. It makes the community's wealth of libraries accessible to everyone. Newbies are no longer excluded from using community libraries by the prohibitive difficulty of setup. In shipping with a package manager, Python joins Ruby, Node.js, Haskell, Perl, Go--almost every other contemporary language with a majority open-source community. Thank you Python.
Of course, that doesn't mean Python packaging is problem solved. The experience remains frustrating. I discuss this in Stack Overflow question Does Python have a package/module management system?.
And, alas for everyone using Python 2.7.8 or earlier (a sizable portion of the community). There's no plan to ship Pip to you. Manual instructions follow.
Python 2 ≤ 2.7.8 and Python 3 ≤ 3.3
Flying in the face of its 'batteries included' motto, Python ships without a package manager. To make matters worse, Pip was--until recently--ironically difficult to install.
Official instructions
Per https://pip.pypa.io/en/stable/installing/#do-i-need-to-install-pip:
Download get-pip.py, being careful to save it as a .py file rather than .txt. Then, run it from the command prompt:
python get-pip.py
You possibly need an administrator command prompt to do this. Follow Start a Command Prompt as an Administrator (Microsoft TechNet).
Alternative instructions
The official documentation tells users to install Pip and each of its dependencies from source. That's tedious for the experienced, and prohibitively difficult for newbies.
For our sake, Christoph Gohlke prepares Windows installers (.msi) for popular Python packages. He builds installers for all Python versions, both 32 and 64 bit. You need to
Install setuptools
Install pip
For me, this installed Pip at C:\Python27\Scripts\pip.exe. Find pip.exe on your computer, then add its folder (for example, C:\Python27\Scripts) to your path (Start / Edit environment variables). Now you should be able to run pip from the command line. Try installing a package:
pip install httpie
There you go (hopefully)! Solutions for common problems are given below:
Proxy problems
If you work in an office, you might be behind a HTTP proxy. If so, set the environment variables http_proxy and https_proxy. Most Python applications (and other free software) respect these. Example syntax:
http://proxy_url:port
http://username:password#proxy_url:port
If you're really unlucky, your proxy might be a Microsoft NTLM proxy. Free software can't cope. The only solution is to install a free software friendly proxy that forwards to the nasty proxy. http://cntlm.sourceforge.net/
Unable to find vcvarsall.bat
Python modules can be part written in C or C++. Pip tries to compile from source. If you don't have a C/C++ compiler installed and configured, you'll see this cryptic error message.
Error: Unable to find vcvarsall.bat
You can fix that by installing a C++ compiler such as MinGW or Visual C++. Microsoft actually ship one specifically for use with Python. Or try Microsoft Visual C++ Compiler for Python 2.7.
Often though it's easier to check Christoph's site for your package.

I think uninstalling and reinstalling python would fix the problem, but before trying that I thought maybe you can help me to find the cause of the problem and the right way to fix this. Thanks.

I was able to solve my problem (on Win 8.1 64bit, Python 3.4.2) with the change suggested here:
https://bitbucket.org/pypa/setuptools/pull-request/122/ensure-py_version-and-platform-are-str-in/diff#chg-pkg_resources/init.py

Instead of downloading ez_setup.py, use get-pip.py instead. From the docs, if setuptools is not installed, it will install it first.
Since you're still getting an error, try installing pip and setuptools from Christoph Gohlke's Python Extension Packages for Windows repository. Make sure you download the 32-bit installers for Python 3.4. Once downloaded, run the .exe files and hopefully everything will be back to normal. There are tons of scientific computing packages there, so if you want numpy linked against Intel's MKL, and scipy, which uses the enhanced version of numpy, go right ahead!

Well it seemed to me that my python installation was completely messed up. It could have been related to a temporary installation of python 2 on my system a few weeks ago. Anyway, I thought it would be easier for me to just uninstall and reinstall the whole thing. So I uninstalled python and then reinstalled, but even that was not enough. Finally, I manually deleted C:\Python34 and reinstalled python and now it works fine.

pip install django timeout on MacOSX Lion

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:

timeout: timed out
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
