我按步骤安装，怎么xlrd不支持xls呢？

源自：2-2 PyCharm的使用

Traceback (most recent call last):

File "C:\my code\test001.py", line 2, in <module>

xlrd.open_workbook('class01.xlsx')

File "C:\my code\venv\lib\site-packages\xlrd\__init__.py", line 170, in open_workbook

raise XLRDError(FILE_FORMAT_DESCRIPTIONS[file_format]+'; not supported')

xlrd.biffh.XLRDError: Excel xlsx file; not supported
