所以我正在做一个项目，使用多个蜘蛛抓取不同的网站。我想让蜘蛛在用户要求继续时说“是”时再次运行。
keyword = input("enter keyword: ")
page_range = input("enter page range: ")
flag = True
while flag:
process = CrawlProcess()
process.crawl(crawler1, keyword, page_range)
process.crawl(crawler2, keyword, page_range)
process.crawl(crawler3, keyword, page_range)
process.start()
isContinue = input("Do you want to continue? (y/n): ")
if isContinue == 'n':
flag = False
但我收到一条错误消息，说反应堆无法重新启动。
