ModuleNotFoundError: No module named scrapy.contrib

貌似我写的时候还没有搜索到其他同学写这个问题，我就写一下吧。。。。。。

我貌似在使用的时候遇到问题：写下载图片使用内置的ImagesPipeline时候

ModuleNotFoundError: No module named 'scrapy.contrib'

也就是

其实报错的原因只是。。。。。他没有这个包。。。因为其实这个包在。。

from scrapy.pipelines.images import ImagesPipeline这样子

所以其实正确的写法，使用内置的是这样子写得（注意我注释的内容）

ITEM_PIPELINES = {
     # 'tupian.pipelines.ImagePipeline': 300,
    'scrapy.pipelines.images.ImagesPipeline': 300
   # 'scrapy.contrib.pipeline.images.ImagesPipeline':300
}

这样子就可以成功使用内置的东西额。。。巨坑。

我的整个setting.py如下

结果如下：e:/img2下面会有full文件夹，full下面就是下载的图片
