基本上，我只需要为Active Admin添加一个Ckeditor表单。
我在为活动管理员集成Rich Gem时遇到了问题。
Rich Gem仅支持Formtastic和1和2，它不支持3，尽管已经完成patch来支持Formtastic 3 +。
我目前正在使用formtastic（〜＆gt; 3.1）。

跑完后，这一行

目前，我正在使用github的activeadmin gem。如果我将其切换为主人，我会遇到其他问题（与AA相关）。

答案 0 :(得分：2)
嗯，这总是最后一个在版本依赖性方面尝试的选项，但解决了这个问题。
下载rich gem并手动将其放在vendor文件夹中。之后，您必须在路线文件
中提及此内容gem 'rich', path: 'vendor/rich(actual folder name)'
然后，您可以执行以下操作
rails generate rich:install
应该好好去，如果你被困在某个地方，请告诉我。
