Sistem brew upgrade
saya ditingkatkan Python ke Python 3.7. Sayangnya, Python 3.7 merusak perangkat lunak lain yang perlu saya gunakan (termasuk tetapi tidak terbatas pada Ansible). Saya membayangkan masalah ini akan teratasi pada minggu depan, tetapi sementara itu, saya ingin mengembalikan ke Python 3.6.5.x
A brew info python
menunjukkan bahwa versi sebelumnya masih diinstal dan tidak dibersihkan:
➜ brew info python

Berbagai brew link
dan brew install
perintah yang disarankan oleh situs lain sepertinya tidak berfungsi:
