小编use*_*092的帖子

我刚刚在运行AMD A8-5600K APU(64位操作系统)的Win 7机器上安装了以下内容

python-2.7.6.msi
matplotlib-1.3.1.win32-py2.7.exe
numpy-1.8.0-win32-superpack-python2.7.exe

我用的时候

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation

我收到此错误消息:

Traceback (most recent call last): 
  File "C:\Python27\MuirsProgs\decay-1.py", line 9, in <module> 
    import matplotlib.pyplot as plt 
  File "C:\Python27\lib\site-packages\matplotlib_init_.py", line 111, in <module> 
    raise ImportError("matplotlib requires dateutil") 
ImportError: matplotlib requires dateutil

我是Python新手,不知道如何解决这个问题.
