This occurs often times because the Gemfile lacks the gems needed for the jquery dependencies to resolve themselves.
这种情况经常发生，因为 Gemfile 缺少 jquery 依赖项自行解决所需的 gem。
In Rails 5.x, add this to the Gemfile:
在 Rails 5.x 中，将此添加到 Gemfile：
gem 'jquery-rails', '~> 4.3', '>= 4.3.3'
gem 'rails-ujs', '~> 0.1.0'
After this, run bundle Install.
在此之后，运行 bundle Install。
Restart the server for it to update the latest changes and voila, it works!
重新启动服务器以更新最新的更改，瞧，它可以工作了！

This is caused because of default javascript runtimes that are already available in Windows but has some compatibility issues. The most easy workaround is to install nodejs from http://nodejs.org/download/and then restart your PC. This solves all the issues.
这是因为默认的 javascript 运行时已经在 Windows 中可用，但存在一些兼容性问题。最简单的解决方法是安装 nodejs http://nodejs.org/download/，然后重新启动您的 PC。这解决了所有问题。

In your controller file you can not tell rails not to use a layout by writing
在你的控制器文件中，你不能通过写来告诉 rails 不要使用布局
layout false
Directly under your controller class on the second line
直接在第二行的控制器类下
class ExampleController < ApplicationController
layout false

Go to gemfile and make sure that gem jquery-railsis uncommented. Run bundle install. That should do it.
转到 gemfile 并确保 gem jquery-rails未注释。运行捆绑安装。那应该这样做。
