使用pip，ImportError安装包

Question

当我使用pip安装数据包时（例如patsy）

[sudo] pip install patsy

Downloading/unpacking patsy
Downloading patsy-0.1.0.tar.gz (258kB): 258kB downloaded
Running setup.py egg_info for package patsy

no previously-included directories found matching 'doc/_build'
Requirement already up-to-date: numpy in /usr/lib/python2.7/dist-packages (from patsy)
Installing collected packages: patsy
Running setup.py install for patsy

no previously-included directories found matching 'doc/_build'
Successfully installed patsy
Cleaning up...

并且pip安装在/usr/local/lib/python2.7/dist-packet/而不是/usr/lib/python2.7/dist-packet/中，当我尝试在Ipython中导入数据包时我有这个错误：

import patsy

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-9de22d189b17> in <module>()
----> 1 import patsy

ImportError: No module named patsy

我有Linux Mint Mate 15.我做错了什么？
