从1.10.beta4升级到Ember.js 1.13.2后，我们再也无法预编译生产中有弃用警告的Handlebars模板。请查看rake资产的错误和追溯：下面的预编译。奇怪的是，我们在生产环境中没有在Mac上出现任何错误，但在Linux构建服务器（Ubuntu）上失败了。
经过调查，似乎ember-template-compiler.js在预编译期间生成了与编译输出混合的弃用警告。这个JS文件中有一条评论，＆＃34; Ember构建工具将在进行生产构建时删除对Ember.deprecate()的任何调用。＆＃34;但我不知道Sprockets工具链是如何工作的。我无法覆盖Ember.deprecate，因为在预编译期间没有包含application.js文件。如果有人能说出如何在Rails资产预编译中删除对Ember.deprecate的调用，那将有助于进一步调试。
我们确实需要摆脱弃用，但可能需要一些时间！感谢您对此问题的帮助。

是的，我对Ember 1.12升级有相同的经验，请参阅https://github.com/emberjs/rfcs/pull/65#issuecomment-114964973弃用打破了构建并阻止了我的项目的发布。我不得不修复阻止的延迟，延迟释放一天
