求助：如何手动安装pdf2docx?
安装的是python3.8.下载了pdf2docx安装压缩包，使用python setup.py install，始终无法成功。错误代码是：
Traceback (most recent call last):
File "setup.py", line 52, in <module>
long_description=load_long_description("README.md"),
File "setup.py", line 25, in load_long_description
long_description = f.read()
UnicodeDecodeError: 'gbk' codec can't decode byte 0xad in position 13: illegal multibyte sequence
另外，通过pycharm安装也无法成功，请问是什么原因呢？
