在新主机上运行我的 Rails 应用程序并从 1.9.3 升级到 Ruby v2.0.0，我收到了这个奇怪的语法错误。它看起来像这样：
Completed 500 Internal Server Error in 178ms
ActionView::Template::Error (/home/action/braindb/app/views/folders/_contents.html.erb:124: syntax error, unexpected keyword_ensure, expecting end-of-input):
121:
122: </script>
app/views/folders/show.js.erb:1:in ` _app_views_folders_show_js_erb__1073772573694008441_69985052296980'
app/controllers/folders_controller.rb:34:in `show'
我不确定我的<script>标签有什么问题，所以我将在此处粘贴文件 (_contents.html.erb)：

现在这些 Javascript 位于我的 _contents.html.erb 文件的底部。
