我正在使用 Mac OSX Yosemite 10.10.5，我正在尝试在笔记本电脑上使用 python 练习数据科学。我在 virtualenv 上使用 python 3.5.1 但是当我安装 pandas 和 matplotlib 时，它们似乎在尝试导入时都存在冲突。两者都有相同的错误，输出为：

>>> import matplotlib

赶紧跑：

export LC_ALL=C

在通过终端访问python之前。

我自己的问题的完美答案是

添加：export LC_ALL=C export LANG=en_US.UTF-8

在你身上 ~/.bash_profile

退出您的终端，然后重新开始，然后您现在可以尝试导入所有内容
