python2 使用openpyxl 报错UnicodeDecodeError: 'ascii' codec can't decode byte 0xd7 in position 20: ordinal not in range(128) 解决方法

# -*- coding: utf-8 -*-
#! /usr/bin/env python
# author: xiao~~

import openpyxl
import sys
reload(sys)
sys.setdefaultencoding('utf-8')

wb2=openpyxl.Workbook()

wb2.save('test1.xlsx')
print('新建成功')

　　附上剪短的代码

将F:\Python27\Lib\mimetypes.py这个文档下屏蔽就可以

我已验证可以成功解决
