我正在尝试编写网络抓取爬网程序以尝试抓取网站，但是我总是收到错误消息“ ReactorNotRestartable”

Question

这是我编写的完整代码：

import pandas as pd
import scrapy 
from scrapy.crawler import CrawlerProcess


class quote_collector(scrapy.Spider):
  name = "quote_collector_spider"

  def start_requests( self ):
    main_url = 'https://www.goodreads.com/quotes?'
    urls = [ 'https://www.goodreads.com/quotes?' ]
    for i in range(98):
        url = main_url+'page='+str(i+2)
        urls.append(url)

    for url in urls:
        yield scrapy.Request( url = url, callback = self.parse )

  def parse( self, response ):

    quote_blocks = response.xpath('//div[@class="quoteText"]')

    my_quotes = []

    for block in quote_blocks:
        quote = block.xpath('text()').extract_first().strip()
        author = block.xpath('.//span[@class="authorOrTitle"]/text()').extract_first().strip()
        ref = block.xpath('.//span/a[@class="authorOrTitle"]/text()').extract_first()

        my_quotes.append([quote, author, ref])

    quotes_df = pd.DataFrame(columns = ['Quote','Author','Referrence'])
    quotes_df = pd.concat(quotes_df, pd.DataFrame(my_quotes, columns = ['Quote','Author','Referrence']))

# initiate a CrawlerProcess
process = CrawlerProcess()
# tell the process which spider to use
process.crawl(quote_collector)
# start the crawling process
process.start()

我得到的错误在这里：

* 在开始的第309行中，文件“ C：\ ProgramData \ Anaconda3 \ lib \ site-packages \ scrapy \ crawler.py” Reactor.run（installSignalHandlers = False）＃阻止调用

文件“ C：\ ProgramData \ Anaconda3 \ lib \ site-packages \ twisted \ internet \ base.py”，行1282，正在运行 self.startRunning（installSignalHandlers = installSignalHandlers）

文件“ C：\ ProgramData \ Anaconda3 \ lib \ site-packages \ twisted \ internet \ base.py”，在startRunning中的第1262行 ReactorBase.startRunning（self）

在startRunning中的文件“ C：\ ProgramData \ Anaconda3 \ lib \ site-packages \ twisted \ internet \ base.py”，行765 引发错误.ReactorNotRestartable（）

ReactorNotRestartable * 请帮助我了解这是什么错误，以及我在这里做错了什么。
