matplotlib 不导入 python3 [重复]

Question

我有 OSX El capitan，尝试在 python 3 中导入 matplotlib 时出现以下错误：

 >>> import matplotlib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/matplotlib/__init__.py", line 1131, in <module>
    rcParams = rc_params()
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/matplotlib/__init__.py", line 975, in rc_params
    return rc_params_from_file(fname, fail_on_error)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/matplotlib/__init__.py", line 1100, in rc_params_from_file
    config_from_file = _rc_params_in_file(fname, fail_on_error)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/matplotlib/__init__.py", line 1018, in _rc_params_in_file
    with _open_file_or_url(fname) as fd:
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/contextlib.py", line 59, in __enter__
    return next(self.gen)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/matplotlib/__init__.py", line 1000, in _open_file_or_url
    encoding = locale.getdefaultlocale()[1]
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/locale.py", line 559, in getdefaultlocale
    return _parse_localename(localename)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/locale.py", line 487, in _parse_localename
    raise ValueError('unknown locale: %s' % localename)
ValueError: unknown locale: UTF-8

我试图删除 matplotlib 文件夹，并使用 pip install matplotlib 重新安装它，它会重新创建它，但它最终给出了同样的错误。 我已经花了半个周末试图找到答案，但没有运气 - 也许有人可以提供帮助。 最好的

找到了解决方案here。基本上你要做的就是在你的 ~/.bash_profile 中添加两行（并重新打开终端窗口）：

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
