openpyxl 库安装之后出现的错误求助=、=

前面的代码给全了先

@weyou
>>> from openpyxl import Workbook
>>> from openpyxl import load_workbook
>>> wb = Workbook()
>>> ws = wb.active

Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
ws = wb.active
AttributeError: 'Workbook' object has no attribute 'active'

@weyou 我重装python之前，openpyxl库文件还是好好地，重装之后就变成这样了
