【python】TypeError: expected str, bytes

python版本：3.7

scrapy版本：1.7.1

 

问题描述

在这个目录下正常生成

(venv) G:\Users\Administrator\PycharmProjects\pythonPratice\code\spider\day04>scrapy genspider tttt itcast.cn
Created spider 'tttt' using template 'basic'
 

在下一级及以下目录生成失败，mySpider及以下为通过scrapy startproject生成

(venv) G:\Users\Administrator\PycharmProjects\pythonPratice\code\spider\day04\mySpider>scrapy genspider tttt itcast.cn

错误信息

TypeError: expected str, bytes or os.PathLike object, not NoneType

 

解决：

将工程全部删除然后重建

#创建工程

scrapy startproject itcast

#进入下一级目录

cd itcast

#创建爬虫

scrapy genspider myspider itcast.com

 

总结

感觉很气，费了将近2个小时最后也不晓得具体的问题原因是什么，但是删了重建又是对的
