照著打的,為什么會出現(xiàn)這種錯誤,是因為我的是python 3 么

Traceback (most recent call last):

? File "C:\Users\Administrator\workspace\PyrhonTest1\src\text_spider\spider_main.py", line 35, in <module>

? ? obj_spider.craw(root_url)

? File "C:\Users\Administrator\workspace\PyrhonTest1\src\text_spider\spider_main.py", line 14, in craw

? ? self.urls.add_new_url(root_url)

TypeError: add_new_url() takes 1 positional argument but 2 were given
