ImportError: cannot import name python_2_unicode_compatible on macOS

When I run cipherscan on macOS 10.14.5 with bash 4 installed using homebrew, I get this error:

./cipherscan server01:443

that would indicate than six package is too old, try updating it

[jozefizso]

I installed the latest version and the error is still present.

[tomato42]

both for python2 and python3?

[DarkCode01]

i have the same problem.

[tomato42]

This error happens only when the python used by cipherscan has six that is older than 1.9.0. Install newer version of six.

See python-ecdsa setup.py file:

I had same message in Django 3.0. I have installed Django 2.2.9. Error is resolved now.
