Failed to Install Python Cryptography Package with Pip and Setup.Py

ERROR: Could not build wheels for cryptography which use PEP 517 and cannot be installed directly

Setting cryptography to version 2.8 in requirements.txt fixed the issue.

Pipenv install fails on cryptography package: Disabling PEP 517 processing is invalid error

It seems the cryptography package can only be installed with pip, not pipenv, so by doing this first...

brew install pkg-config libffi openssl
env LDFLAGS="-L$(brew --prefix openssl)/lib" CFLAGS="-I$(brew --prefix openssl)/include" pip install cryptography

(Commands taken from this question.)

...I could then run pipenv install which built and installed everything fine.
