assert path.is_file() exception: no description

[HAOGUOKAI]

When I execute the 'force' file, the code within the 'init.py' file: path = Path.home() / '.force' / 'machine.json' assert path.is_file() produces the error message "exception: no description." This is likely due to the miss of the 'machine.json' file, but I can't find it.
