非常简单的python scrapy豆瓣爬虫，但是总是报错？

Question

题目描述

看视频跟着老师做的scrapy豆瓣电影top250爬虫，老是报错，查了csdn很多文章，弄来弄去都报错！！

题目来源及自己的思路

真-小白，第一次接触scrapy，不知道py文件这些怎么安放

不知道这样对不对，请大神们帮我揪出错误，查了很多，无果！！

相关代码

【这是spider.py】
from scrapy.spiders import CrawlSpider

class Douban(CrawlSpider):

name="douban"
start_url=["https://movie.douban.com/top250"]

def parse(self,response):
    print(response.body)
    print(response.url)

【这是main.py】
from scrapy import cmdline
cmdline.execute("scrapy crawl douban".split())

你期待的结果是什么？实际看到的错误信息又是什么？
