javascript - “Caller”， 'Callee'，使用 Yeoman 部署时 Angular 应用程序出现严格模式错误

Question

我使用 Yeoman 的 Angular 生成器构建了一个 Angular 应用程序，它在本地完美运行。然而，当部署到heroku时，什么也没有显示。控制台错误是“未捕获的类型错误:‘调用者’、‘被调用者’和‘参数’属性可能无法在严格模式函数或调用它们的参数对象上访问”。

我想我已经将其追溯到 Grunt 构建任务，它将所有 js 文件和 html 文件一起压缩。有没有一种方法可以简单地将 js 连接到单个文件中而不是缩小以避免这些问题？

这是我的 Gruntfile.js

您可以使用参数数组，但在严格模式下不能使用被调用者或调用者。这是 JavaScript 的事情。它与 Angular、yeoman、minification、heroku 或其他任何东西都没有任何关系。
