問題描述

在這個目錄下正常生成

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

在下一級及以下目錄生成失敗，mySpider及以下為通過scrapy startproject生成

解決：

將工程全部刪除然后重建

#創(chuàng)建工程

scrapy startproject itcast

#進入下一級目錄

cd itcast

#創(chuàng)建爬蟲

scrapy genspider myspider itcast.com

?

總結(jié)

感覺很氣，費了將近2個小時最后也不曉得具體的問題原因是什么，但是刪了重建又是對的
