python - django 动态蜘蛛错误 "check_mandatory_vars"

Question

我正在使用 Django-dynamic-spider 库来构建动态抓取工具。适用范围是抓取网站并将数据动态保存到我的数据库。从我将它渲染到我的 Django 应用程序的地方，自动将它与上下文一起呈现。但是当我用命令运行它时

scrapy crawl article_spider -a id=1 -a do_action=yes

我收到以下错误:

当我从 sourceforge 尝试 pywin32 时，它发生在我身上。请从这里下载包 link .确保您的 pip 已升级到最新版本。您可以像“easy_install --upgrade pip”或“pip install --upgrade pip”一样升级它。然后从给定位置重新安装 pywin32。希望它对你有用。如果您仍有问题，请告诉我。
