而在python中导入xlrd和xlwt获取错误消息

Question

我正在尝试在Windows中的python中导入xlrd和xlwt模块并收到以下错误消息，请建议如何解决它。

导入xlrd

时

import xlrd

Traceback <most recent call lst>:
File "<stdin>", line 1,in <module>
File "c:\Python33\lib\site-package\xlrd\__init__.py", line 3, in <module> from info import __Version__
ImportError : No module named 'info'

导入xlwt

时

import xlwt


Traceback <most recent call lst>:
File "<stdin>", line 1,in <module>
File "c:\Python33\lib\site-package\xlwt\__init__.py", line 10, in <module> from    Workbook import Workbook
ImportError : No module named 'Workbook'

谢谢， 尼拉吉
