在OS X上使用Python自制软件
我一直在使用Mac python，而且我决定自学matplotlib ，因为我想用一些常用模块的经验。 我听到大家的意见，一旦你进入非标准模块，最好使用python扔自制软件，所以你有权访问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去python shell。 一旦那里，我运行import matplotlib.pyplot as 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，我仍然使用mac python，而不是酿造的python，我试图编辑path，但它不工作，即使我在每次编辑后运行$source ~/.bash_profile 。 以防万一我正在编辑path错误，我将发布文件内容如下：

$pip3 install matplotlib返回以下内容

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

你可以通过使用which python来检查命令来自哪里。 在这种情况下，您正在将/opt/local/bin/到您的path中，但是您之前正在添加/Library/Frameworks/Python.framework/Versions/2.6/bin和/usr/local/bin/在每种情况下）。 $ PATH在第一次成功的匹配时停止，所以你不会从/opt/local/bin选取python。 尝试将该行移动到您的bashrc的末尾，或将其添加到$ PATH的前面。
