我安装了熊猫，但在导入时却出现错误

Question

这是我在IDLE（Python 3.8 64位）中导入熊猫时遇到的错误。

>>> import pandas
Traceback (most recent call last):
  File "<pyshell#9>", line 1, in <module>
    import pandas
  File "C:\Users\hp\AppData\Local\Programs\Python\Python38\lib\site-packages\pandas\__init__.py", line 11, in <module>
    __import__(dependency)
