这是什么错误？有人可以帮忙吗？
答案 0 :(得分：0)
我认为这不是ActiveAdmin问题，而是与Windows上的ExecJS有关。我认为ExecJS::RuntimeError on Windows trying to follow rubytutorial可能就是你要找的东西。
答案 1 :(得分：0)
这不是ActiveAdmin问题，也许在您在app / assests / javascript .js或.coffee文件中编写时，还会编写一些不必要的代码，所以请检查一下
答案 2 :(得分：0)
从application.js中删除行// = require_tree，它消除了我的错误
