【问题讨论】：

我建议你使用 Instagram API 而不是使用 scrapy。使用 API 解析和爬取页面，您不会感到痛苦

标签： python web-scraping scrapy instagram instagram-api

【解决方案1】：

根据输出，您使用的是非常非常旧的 Scrapy 0.14.4，它没有将 Spider 暴露到 scrapy 命名空间中。

任一更新：

pip install scrapy --upgrade

或者，将您的导入更改为（不确定这是否可以正常工作）：

from scrapy.spider import BaseSpider as Spider

【讨论】：

确认从 scrapy.spider import BaseSpider as Spider 工作但不是升级。 pastebin.com/6YB0TZRs 谢谢！
@MonaJalal 是的，由于某种原因，您基本上无法安装最新的scrapy 版本。它报告它正在安装，但scrapy 命令仍然“绑定”到 0.14.4。很高兴解决方法奏效了，尽管我会努力使升级成为可能 - 0.14.4 真的非常老了 - 从那时起很多事情都发生了变化。
你能看看这个问题吗？ stackoverflow.com/questions/42545020/…

【解决方案2】：

你可能需要通过你的包管理器升级scrapy，看来你使用的是基于Linux的操作系统。

如果您有 Python 2 和 3，请尝试同时使用 pip2 和 pip3 进行升级
