python pandas和matplotlib安装冲突

Question

我使用的是macosxyosemite 10.10.5，我试图在笔记本电脑上用python练习数据科学。我在virtualenv上使用python3.5.1，但是当我安装pandas和matplotlib时，它们似乎在试图导入时发生冲突。两者都有相同的错误，输出为：

>>> import matplotlib
Traceback (most recent call last):

  File "/Users/deanarmada/.virtualenvs/python3-data-science/lib/python3.5/site-packages/matplotlib/__init__.py", line 1131, in <module>

    raise ValueError('unknown locale: %s' % localename)
ValueError: unknown locale: UTF-8

Answer 1

对我自己的问题最好的答案是

添加： 导出LC_ALL=C 导出LANG=en_美国UTF-八

在你~/.bashéu个人资料上

退出终端，然后重新开始，现在可以尝试导入所有内容

Answer 2

只需运行：

export LC_ALL=C

在通过终端访问python之前。在
