老師你好，對著你的代碼，我編譯出現(xiàn)這個，我的是3.6版本
Traceback (most recent call last):
? File "D:\Python\spider_main.py", line 33, in <module>
? ? obj_spider.craw(root_url)
? File "D:\Python\spider_main.py", line 13, in craw
? ? self.urls.add_new_url(root_url)
TypeError: add_new_url() takes 1 positional argument but 2 were given

好了，終于運行成功啦！我又看了好幾遍視頻，原來是UrlManager下的def add_new_url(self,url):這個少寫了一個參數(shù)
