Please help me with the python UnicodeDecodeError when run the project using cocos command

I’m new here. I follow the workflow steps here to try to build up the environment. I get a UnicodeDecodeError when I try to run a project using the cocos command:

cocos run -p web

The error shows:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xb0 in position 1: ordinal not in range(128)

Anyone knows about this error? Please help my fix it. Thank you very much!

What is the version of your python?
Maybe add sys.setdefaultencoding('utf-8') ?
