        初入scrapy,利用anaconda作为开发环境,通过AnacondaPrompt安装Scrapy拓展库,虽然成功安装了,但是import的时候出现了问题         网上巴拉巴拉一大堆,经过长时间的搜索踩坑搜索又踩坑之后,找到了一篇解决方案,那就是把scrapy版本下调(Ps:本人原来的Scrapy版本是2.6.2的,自行删除后重新选择了2.5.1的),具体操作如下:pipuninstallScrapy 卸载原拓展库        pipinstallScrapy==2.5.1 安装2.5.1版本scrapy库可能有的人在这一步问题已经解决了,下面可以不用注意问题来了:
