I found several possible fixes on Stack Overflow, but they all failed because six 1.4.1 could not be uninstalled. The operating system ships that version with its framework-based Python installation. System Integrity Protection prevents it from being removed, even by the root user.

The simplest solution is to install and use your own Python. Other approaches are discussed in this pip issue.

Terminal window
brew install python
