我有python 3.2.3在windows上。安装matplotlib
我正在努力做到这一点：

import matplotlib.pyplot as plt

我明白了：

Traceback (most recent call last):
File "<pyshell#10>", line 1, in <module>
import matplotlib.pyplot as plt
File "E:\programs\python 3.2.3\lib\site-packages\matplotlib\pyplot.py", line 24, in <module>
import matplotlib.colorbar

File "E:\programs\python 3.2.3\lib\site-packages\matplotlib\textpath.py", line 5, in <module>
import urllib.request, urllib.parse, urllib.error
ImportError: No module named urllib.request

有什么想法吗？
