PyPDF2 导入错误：无法从部分初始化的模块“集合”中导入名称“ChainMap”（很可能是由于循环导入）

Question

I am using python 3.9 and installed PyPDF2 using pip3 install pypdf2 . When I try to import PyPDF2 , I get the following error:

"File "C:\Users\mertk\AppData\Local\Programs\Python\Python39\lib\string.py", 
line 53, in <module>
from collections import ChainMap as _ChainMap
ImportError: cannot import name 'ChainMap' from partially initialized module 
'collections' (most likely due to a circular import)" 
C:\Users\mertk\AppData\Local\Programs\Python\Python39\
lib\collections\__init__.py)

How can I fix this?

Thanks.

There is an issue with your installed pypdf2 module. Uninstall it and reinstall it using the following command

pip install pypdf2 --force-reinstall

after that if you're still getting errors make sure you import ChainMap using

from collections import ChainMap
