ruby-on-rails - 会话中发生 ActionView::Template::Error #new：activeadmin 找不到文件“active_admin/nested_menu_arrow.gif”

问题描述

从 Rails 5.0.1 升级到 5.2.0 后，活动管理员升级（从 1.0.0.pre5 到 2.6.0）现在我得到：

An ActionView::Template::Error occurred in sessions#new:

  couldn't find file 'active_admin/nested_menu_arrow.gif'

解决方案

在谷歌上挖掘之后，我终于找到了这个链接：

https://git.rarolabs.com.br/rarolabs/active_admin/tree/1a16239be31d40307f3fee972e91ca15b9341167/app/assets/images/active_admin

我做了什么，我下载了必要的资源并保存在我的项目路径中的相应位置。这解决了问题。
