我想在Mac（10.7.5 Lion）中安装Matplotlib，其中python（2.7.1），pip（8.1.2），numpy（1.11.0），astropy（1.2）已经安装并正在工作如预期。首先，我试着用命令安装Matplotlib
sudo pip install matpltlib
，它表明Matplotlib 1.5.1已成功安装。但是，当我进入蟒蛇和类型import matplotlib这表明这样的错误消息：
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Python/2.7/site-packages/matplotlib/__init__.py", line 1131, in <module>
rcParams = rc_params()

encoding = locale.getdefaultlocale()[1]

return _parse_localename(localename)

raise ValueError, 'unknown locale: %s' % localename
ValueError: unknown locale: UTF-8
我不明白，究竟是什么问题。我打开了所有这些.py文件，并且已经读取了指定行中的命令。由于这些是只读文件（甚至是根目录），因此无法编辑任何内容。我不知道如何解决这个问题。
好吧，我再由PIP卸载它，并试图从source.When安装我尝试（下载280 MB的源文件后）通过python setup.py build打造它，它最终将几个错误，如这个 -
src/_macosx.m:2494: warning: implicit conversion shortens 64-bit value into a 32-bit value
src/_macosx.m:1337: error: ‘for’ loop initial declaration used outside C99 mode

lipo: can't open input file: /var/tmp//ccLauouU.out (No such file or directory)

我查过了，没有名为var的目录。我无法调试这个了。
命令'locale'（在你的终端中，不是Python）产生了什么？您似乎具有无效的区域设置配置。 –
它产生 “LANG = LC_COLLATE =” C “ LC_CTYPE = ”UTF-8“ LC_MESSAGES = ”C“ LC_MONETARY = ”C“ LC_NUMERIC = ”C“ LC_TIME = ”C“ LC_ALL = ” – Sanskriti
注意你的'LC_CTYPE'变量;应该将语言环境变量设置为语言代码，再加上一个点和一个字符集。将它设置为'LC_CTYPE =“en_US.UTF-8”';你可能想找到它的位置。 –
