What is your Python version? This project is only working with Python 2 at the moment

？？？ 为什么 2020 年还用 python 2 ？

[duguyue100]

Because the project was initially written 3 years ago (original author graduated) and many specifics only apply to Python 2 (see README as well). It only takes you a few minutes to install a Python 2 environment.

Thanks. I apologize for my rudeness.
