我在创建新的 Rails 应用程序时遇到问题。我创建了一个测试并复制了我的命令提示符，让你看看会发生什么。

故事是这样的：我可以制作应用程序，启动测试服务器，然后获取页面。然后，我可以为 Pages 生成一个控制器，其中包含一个名为 home 的页面。它创建后，我重新启动服务器。现在，这是发生崩溃和错误的地方。

在我的 URL 栏中，第二个我为 Pages 键入“/p”，错误消息在我的提示中生成。

    'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

我发现问题实际上出在注册表中的一个杂散变量上。对于我的课，我们设置了 sublime text 2 有一个直接在命令提示符下打开的快捷方式（它在 Mac 上自动打开）

这是我摆脱的价值，还重新安装了node.js

快速解决方法可能是：//= require_tree .从application.js

然后，重新启动服务器并重试。

更新：

导航\app\views\layouts\application.html.erb

将第 6 行从：

'<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>'

至

<%= javascript_include_tag 'defaults', 'data-turbolinks-track' => true %>

看看有没有用！
