最近，我正在尝试 CodeRunner（2.2.2 版）。我的 python 是 miniconda2，一个科学的 python。我可以导入 numpy，但我不能导入 pandas。这很棘手！

我尝试了一些解决方案，例如：https ://coderwall.com/p/-k_93g/mac-os-x-valueerror-unknown-locale-utf-8-in-python 。但它没有成功。

import numpy as np
print 'numpy imported!'
print '----------------------Success-----------------------------------'
import pandas as pd

错误

numpy imported!
----------------------Success-----------------------------------
