ImportError：即使已安装模块，也没有名为请求的模块

Question

I'm running Mac OS X and Python (version 2.7). Apparently I'm missing requests , but it should be installed.

$ python setup.py 
Traceback (most recent call last):
  File "setup.py", line 1, in <module>
    import requests
ImportError: No module named requests

$ pip install requests
Requirement already satisfied: requests in /usr/local/lib/python2.7/site-packages
