Thanks!

I installed gnureadline. I could not rename the readline.so file as the
file moved to the /System/Library path in Mac High Sierra.

FWIW I am not using the system python, but Anaconda 3 python (ipython
6.4.0).

Python 3.6.5 |Anaconda custom (64-bit)| (default, Apr 26 2018, 08:42:37).

Is there anything else I should try?
