ImportError: matplotlib requires dateutil

问题

I have successfully installed matplotlib with python 2.6 on x64 Windows7. When I try to import matplotlib, it shows the following error. I have also installed numpy following this link: Installing Numpy on 64bit Windows 7 with Python 2.7.3

import matplotlib.pyplot as plt

Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    import matplotlib.pyplot as plt
  File "C:\Python26\Lib\site-packages\matplotlib\__init__.py", line 110, in <module>
    raise ImportError("matplotlib requires dateutil")
ImportError: matplotlib requires dateutil

How can I make it work?

I installed matplotlib-1.3.0.win-amd64-py2.6.exe from http://matplotlib.org/downloads.html

You're probably looking for:
