OS X pip3 не работает с Brew установить Python3.6.5_1

Question

Я только что сделал новую установку python3 (3.6.5_1) на Mac OS (High Sierra), и pip3 не работает. Я получаю следующую ошибку с pip3:

Traceback (most recent call last):

which pip3 возвращается /usr/local/bin/pip3

Я искал и не могу найти решение.
