首先借用github上的解答链接

% python3 -m venv venv
% source ./venv/bin/activate
[venv] % pip install pypdf2==1.26.0
[venv] % python test.py
1.26.0

[venv] % pip install pypdf2==1.27.3
[venv] % python test.py
1.27.3

可以看到在版本为1.26.0时，可以正常运行，而默认安装的版本一般可能会是1.27以上，就会报错

所以要解决这个问题就只用

pip install pypdf2==1.26.0

之后就可以正常运行了
