sys.__stdout__.encoding指的是什么呢？根据 'utf-8' codec can't decode byte 0xc8 in position 3: invalid continuation byte
应该是utf-8
方法一：
我们把73行的sys.__stdout__.encoding改为‘gbk’ 就万事大吉了。
具体为什么是‘gbk ’ 因为被‘gbk’虐太多次了一有问题基本上就是这个玩意，也可能是Windows系统的原因
ctrl+s保存下
重新输入安装命令pip install Scrapy
安装成功后，我选择把sys.__stdout__.encoding改回去（虽然以后都在win下弄，但还是小心点好。。），小心翼翼的
方法二（未测试）：
import sys
sys.setdefaultencoding('gbk')
#把sys.__stdout__.encoding改成‘gbk’ ？
