我正在使用ember框架为我的前端应用程序，它一直很好，直到上周现在，当我试图建立应用程序得到以下问题，

Build failed.
Build Canceled: Broccoli Builder ran into an error with `UglifyWriter` plugin. 💥
SyntaxError: Unexpected token: name (v)

请查找以下package.json以供参考

我看到一些依赖项被拉到了最新版本的uglify：3.11.3，这可能会导致一个问题，但我不知道如何指导他们使用2.7.0版本或不会导致问题的版本。我不知道如何覆盖嵌套的依赖项。
有人能指导我解决这个问题吗？

修复程序1：

我已经通过在ember-cli-build.js中添加以下代码修复了该问题

module.exports = function(defaults) {
  var app = new EmberApp(defaults, {
    // Add options here
    minifyJS: {
      options: {
        exclude: ["**/vendor.js"]
      }
    }
  });

但我不确定这是否是一个好的解决方案，但它解决了我的问题。
