几天来,我一直试图在Scrapy中创建一个爬虫程序,每个项目都会出现相同的错误:spider not found
。无论我做了什么更改或遵循了哪个教程,它总是返回相同的错误。
有人能告诉我应该在哪里寻找错误吗?
谢谢您!

编辑
正如eLRuLL建议的那样,我将
_init_.py
文件添加到spider
文件夹中,同时也将scrapy.spider更改为scrapy.spider s,因为它告诉我它已被清除。现在cmd返回的结果是:C:\Users\nastea\Desktop\scrapscrapy>scrapy crawl ss

最佳答案
似乎您的__init__.py
文件夹中的spiders
文件发生了问题。
尝试自己添加(保留为空):
───spiders
__init__.py
SSSpider.py
SSSpider.pyc
