win7环境scrapy输出错误日志报错解决方案

Traceback (most recent call last):
File "d:\python27\lib\logging\__init__.py", line 884, in emit
stream.write(fs % msg.encode("UTF-8"))
UnicodeDecodeError: 'gbk' codec can't decode bytes in position 1274-1275: illegal multibyte sequence
Logged from file scraper.py, line 158

各种尝试均告失败，后来在论坛中发现有人说这个bug在python3环境不存在，于是尝试升级python2.7的logging组件。

Shell代码

pip install --upgrade logging

升级logging后再无此报错出现。
