1.安装python并配置好环境变量
2.更新pip ，这步操作时遇到了问题，更新超时了，所以加上--default-timeout来解决超时问题：python -m pip --default-timeout=100 install --upgrade pip
3.安装lxml ：pip intsall lxml
4.安装wheel： pip install wheel
5.在python lib网站上以下安装包，然后使用pip install xxx 安装：
Twisted-18.9.0-cp37-cp37m-win_amd64.whl
pywin32-224-cp37-cp37m-win_amd64.whl
Scrapy-1.6.0-py2.py3-none-any.whl
Python Lib网站：https://www.lfd.uci.edu/~gohlke/pythonlibs/
6.Scrapy调试，验证是否安装成功：
C:\Users\admin>scrapy
