使用ember-template-compiler預編譯Rails失敗

Question

從1.10.beta4升級到Ember.js 1.13.2後，我們不再能夠預編譯Handlebars模板，該模板在生產中存在棄用警告。請參閱下面的rac資源的錯誤和回溯：precompile。奇怪的是，我們在生產環境中沒有在Mac上出現任何錯誤，但在我們的Linux構建服務器（Ubuntu）上失敗。

在調查中，似乎ember-template-compiler.js在預編譯期間生成棄用警告它與編譯後的輸出混合在一起。這個JS文件中有一條評論，「Ember構建工具將在生成構建時刪除對Ember.deprecate()的任何調用。」但我不知道這是如何與Sprockets工具鏈一起工作的。我無法重寫Ember.deprecate，因爲在預編譯期間沒有包含application.js文件。如果有人可以說如何調用Ember.deprecate在Rails資源預編譯中被移除，它將有助於進一步調試。

我們確實需要擺脫棄用，但可能需要一些時間！感謝您對此問題的幫助。

版本信息（我們不使用燼-CLI）：

• 的Rails 4.2.0
• 燼護欄寶石0.16.1
• 理髮寶石0.9.0
• ember-模板compiler.js 1.13.2

是的，我有與Ember 1.12升級相同的經驗，請參閱https://github.com/emberjs/rfcs/pull/65#issuecomment-114964973反對破壞了構建並阻止了我的項目發佈。我不得不修覆被阻止的貶值，延遲發佈一天
