为什么 rails 没有显示网页

Question

每次启动 rails 应用程序时，服务器都会显示一条错误消息。例如（这是来自命令行）：

Started GET "/" for 127.0.0.1 at 2016-01-10 00:12:31 -0600
Processing by WelcomeController#index as HTML
Rendered welcome/index.html.erb within layouts/application (3.0ms)

我该如何解决这个问题？

Answer 1

尝试删除 javascript_include_tag（指示为断开的行）并查看页面是否加载。如果页面确实加载了，那么关于 javascript.

的资产文件可能有问题

Answer 2

第一种方法解决。在文件中添加application.js这一行：

//= require turbolinks

第二种解决方法 In Gemfile set version 1.8.0 for gem 'coffee-script-source' :

gem 'coffee-script-source', '1.8.0'
