安装python2.7

下载py官网msi安装

python -m pip install --upgrade pip

安装scrapy，附上两个镜像地址，比官网快的不是一点半点

pip install -i https://douban.com/simple scrapy

pip install -i https://pypi.douban.com/simple scrapy

py2安装报错：

error: Microsoft Visual C++ 9.0 is required (Unable to find vcvarsall.bat). Get it from http://aka.ms/vcpython27

安装scrapy需要Microsoft Visual C++ 9.0支持，官网下载

其他命令报错，多试两遍
