Question

我已经通过Anaconda环境在Pycharm中安装了scrapy，并且我可以毫无问题地导入scrapy。我正在尝试使用以下代码从著名的网站上刮掉著名的报价（到目前为止非常简单）

import scrapy


class QuotesSpider(scrapy.Spider):
name = "quotes"

start_urls = [
    'http://quotes.toscrape.com'
]

def parse(self, response):
    title = response.css('title').extract()
    yield {'titletext':title}

但是，当我使用抓取抓取方式运行python文件时，却收到了跟随错误

During handling of the above exception, another exception occurred:

    raise KeyError("Spider not found: {}".format(spider_name))
KeyError: 'Spider not found: Scrapecode'

我知道我没有以正确的方式安装Scrapy，只是通过pycharm安装了它，但这一直给我带来错误。我以为这可以解决问题，但我真的无法弄清楚这些错误。

找不到KeyError ScrapeCode
