Ember发送无法找到预设的“es2015”）

我正在使用Ember构建一个Web应用程序 . 我用 ember new test-app 创建了项目，并且没有对生成的文件进行任何更改 . 当我运行 ember serve 时，我立即收到以下错误：

The Broccoli Plugin: [BroccoliMergeTrees: Addon#compileAddon(ember-welcome-page) ] failed with:

我提到this question寻求帮助，但在尝试解决方案后仍然收到同样的错误 .

我在macOS High Sierra上运行ember-cli v2.16.2和node v8.9.0 . 在我的节点安装中，我安装的唯一三个全局模块是bower，broccoli-cli和ember-cli .
