Question

所以我开始使用ember-rails并且我遇到了一个最令人烦恼的问题。

Ruby 2.1.0，Rails 4.0，Ember 1.10.0，Ember-Data 1.0.0-beta14.1，Ember-rails 0.16.1

我已经查阅过文档，谷歌和wonderful example app，但我没有太多运气。我确定我做错了什么，但我无法弄清楚那可能是什么。

错误：

Application.html.erb

<body style="padding-top: 60px;">

index.html.erb为空

的application.js

//= require jquery-ui
//= require best_in_place
//= require jquery_ujs

    LOG_BINDINGS: true,

application.handlebars

{{render "navbar"}}
<div class="container-fluid">
    {{outlet}}
</div>

修改

我应该指出我有

config.ember.variant = :development

in development.rb

修改

我＆＃34;修复＆＃34;这是通过为ember * gems和ember-rails的所有依赖项进行gem卸载然后重新安装它们。仍然不确定发生了什么。

Answer 1

其他人的简短版本：升级到ember-rails 0.16.2（或更高版本）并将把手从v3降级为v2。

重新安装升级你过去this checkin ember-rails 0.16.1正在添加把手v3，导致'无法找到变量：窗口'问题。 ember-rails 0.16.2解决了这个问题。

ember-rails：编译器说：ReferenceError：找不到变量：window
