Error 'unknown locale: UTF-8' on 'pandas' import (Mac OS X) when running fish shell [duplicate]

问题

I've recently upgraded to Python 3.5 and the newest version of pandas pandas (0.17.1), but this broke the package for me. I'm on Mac OS X 10.9.5, using the fish shell. What can I do?

回答1:

for fish shell

set -x LC_ALL en_US.UTF-8 
set -x LANG en_US.UTF-8

回答2:

Make sure you have your terminal set to export appropriate locale variables, as described in this answer, and that your region is set correctly in System Preferences.
