我试着把scravyd和scrappy连用。
当我使用下面的代码时，它工作正常。

import scrapy
from scrapy.selector import Selector
from scrapy.spiders import CrawlSpider
from shikari.items import shikariItem
from scrapy.http import Request

class Radiate(scrapy.Spider) :
  name = "run"

  allowed_domains = ["google.com"]
  start_urls = ['http://google.com']

  def parse(self, response) :
    item = shikariItem () 
    sel = Selector (response)
    item['url'] = response.url
    return item

但当我把它和 selenium 一起使用时，它就不会

import scrapy
from pyvirtualdisplay import Display
from selenium import webdriver
from shikari.items import shikariItem

class Radiate(scrapy.Spider) :
  name = "run"

  allowed_domains = ["google.com"]
  start_urls = ['http://google.com']

  def __init__(self):
   display = Display(visible=0, size=(800, 600))
   display.start()
   self.driver = webdriver.Chrome('/usr/bin/chromedriver')  

  def parse(self, response) :
    item = shikariItem () 
    item['url'] = self.driver.get(response.url)
    return item

  def teardown(self): 
    display.stop()
    self.driver.close()

我的蜘蛛从来没有运行过。在作业中，它被列在“已完成”下，在错误日志中，我看到exceptions.TypeError: __init__() got an unexpected keyword argument '_job'。
下面是完整的错误日志

我需要做什么才不会收到错误？
