到目前为止，这是我的scrapy代码：
import scrapy
class Tripadvisor(scrapy.Spider):
name = 'Trip_advisor'
url = ['https://www.tripadvisor.com/Hotel_Review-g188644-d604560-Reviews-Sofitel_Brussels_Europe-Brussels.html']
def parse(self,response):
SET_SELECTOR = '.ratings_chart'
for data in response.css(SET_SELECTOR):
Excellent_Selector = '//*[@id="taplc_location_detail_overview_hotel_map_pins_default_0"]/div/div[2]/div[2]/div[1]/div[2]/ul/li[1]/span[3]'
VeryGood_Selector = '//*[@id="taplc_location_detail_overview_hotel_map_pins_default_0"]/div/div[2]/div[2]/div[1]/div[2]/ul/li[2]/span[3]'
Average_Selector = '//*[@id="taplc_location_detail_overview_hotel_map_pins_default_0"]/div/div[2]/div[2]/div[1]/div[2]/ul/li[3]/span[3]'
Poor_Selector = '//*[@id="taplc_location_detail_overview_hotel_map_pins_default_0"]/div/div[2]/div[2]/div[1]/div[2]/ul/li[4]/span[3]'
Terrible_Selector = '//*[@id="taplc_location_detail_overview_hotel_map_pins_default_0"]/div/div[2]/div[2]/div[1]/div[2]/ul/li[5]/span[3]'
yield {
'Excellent': data.xpath(Excellent_Selector).extract_first(),
'Very Good': data.xpath(VeryGood_Selector).extract_first(),
"Average": data.xpath(Average_Selector).extract_first(),
"Poor":data.xpath(Poor_Selector).extract_first(),
"Terrible":data.xpath(Terrible_Selector).extract_first()
}
每当我在项目目录中运行scrapy crawl Trip_advisor时，我都会收到KeyError: Spider not found: Trip_advisor，如何修复此错误？
我很困惑，因为我明确在Trip_advisor类中定义了Tripadvisor名称。
编辑：命令行中的回溯错误，感谢@furas
