Python Run error Unicodedecodeerror

Python2.7 has a bug on Windows that runs an error:

Unicodedecodeerror: ' ASCII ' codec can ' t decode byte 0xc4 in position 33:ordinal not in range (128)

The solution is as follows:

Edit the python27\lib\mimetypes.py file, select All, replace with the correct script after the patch below, or modify it directly from this patch:

"" Guess the MIME type of a file. This module defines the useful functions:guess_type (URL, strict=1)-guess the MIME type and encoding of a URL.
