我已经使用Mac python一段时间了,我决定自学matplotlib,因为我想拥有一些常见模块的经验.我听到大家说,一旦你进入非标准模块,最好使用python threw homebrew,所以你可以访问pip而不是easy_install.运行后：$brew install python –with-brewed-openssl,$brew install python3 –with-brewed-openssl,$pip install matplotlib,我用$python3转到python shell.在那里,我运行import matplotlib.pyplot作为plt,并得到以下内容：
Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 00:54:21)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib.pyplot as plt
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'matplotlib'
>>>
我有一种感觉我仍在使用mac python,而不是brewed python,我已经尝试编辑路径,但它无法正常工作,即使我在每次编辑后运行$source~ / .bash_profile.为了防止我编辑错误的路径,我将在下面发布文件内容：

$pip3 install matplotlib返回以下内容
RuntimeError: Broken toolchain: cannot link a simple C program

如果需要更多信息,请随时询问,并提前感谢您的帮助！
解决方法:
如果你的系统中有两个python版本,pip通常会为python2安装模块,所以对于python3你可能需要使用pip3.
