我正在尝试在 heroku 实例上部署一个使用nested_inline的 django 应用程序。一切都在本地运行良好，但在收集静态期间我在 heroku 服务器上遇到错误。
我按照heroku 指南获得了一个最小的 django 设置工作。然后我将“django-nested-inline”添加到我的 requirements.txt，将“nested_inline”添加到我的 INSTALLED_APPS 的末尾，并将“从 nested_inline.admin 导入 NestedModelAdmin，NestedStackedInline”添加到我的 admin.py。
一切仍然在本地完美运行，没有任何问题。但是当我推送到heroku“git push heroku master”时，出现以下错误：
$ git push heroku master

正如它所说，forms-nested.css文件引用了类似的图像nav-bg.gif，据我所知，这些图像似乎不存在于任何地方。但这并不能阻止 django 和 nested_inline 在本地正常工作。我不确定为什么它会破坏heroku？
