无法导入明确安装的模块

安装机械化后，我似乎无法导入.

After installing mechanize, I don't seem to be able to import it.

我尝试从此仓库通过pip，easy_install并通过python setup.py install安装: https://github. com/abielr/mechanize .所有这些都无济于事，因为每次我进入Python交互式页面时，我都会得到:

I have tried installing from pip, easy_install, and via python setup.py install from this repo: https://github.com/abielr/mechanize. All of this to no avail, as each time I enter my Python interactive I get:

Python 2.7.3 (default, Aug  1 2012, 05:14:39) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import mechanize
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named mechanize
>>> 

我之前运行的安装报告说它们已经成功完成，因此我希望导入能够正常进行.是什么原因导致此错误?

The installations I ran previously reported that they had completed successfully, so I expect the import to work. What could be causing this error?
