项目是 rails 做服务器，vue 写后台管理调接口。在使用 mina 部署的时候，执行“mina staging deploy”命令的时候，报错：

部署配置文件是 staging.rb:

主要是这句错“Sprockets::FileNotFound: couldn't find file 'jquery' with type 'application/javascript'”，因为是用 vue 写的界面，app/assets 下并没有什么 js 文件，只有这些：

不知道为什么还报这个错。而且“Files /usr/local/ruby/workspace/nextdoor_staging/current/app/assets/config/manifest.js and ./app/assets/config/manifest.js differ”说两个文件不一样，但都是同一个 git 的分支 pull 下来的，应该是一样才对。 求各位解答指点一下，O(∩_∩)O 谢谢
