Python 模块未安装

Question

我有一些运行很好的代码，但在一天的过程中，我破坏了一些东西，现在我无法安装任何 python 模块。具体来说，我需要 numpy、matplotlib 和 pillow。我无法安装任何一个。

但奇怪的是它们似乎都安装得很好：

$ sudo pip install numpy
Collecting numpy

Installing collected packages: numpy
Successfully installed numpy-1.11.0

或者当我尝试时：

$ python

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

它为我尝试安装的任何模块执行此操作。任何帮助将不胜感激。

这是默认 python 和默认 pip 不匹配的结果。为确保软件包安装到正确位置，请使用：

python -m pip install $PACKAGE

这导致运行将 pip 分配给所需的 python 而不是在您的路径中找到的第一个。
