Windows 10 下面，Ruby 2.x 后 irb 输入不了中文，有没有办法可以解决？

ahtest — Thu, 07 Nov 2019 08:53:12 +0800

ruby 2.3.3 系统：win 10 在 cmd 下输入中文时，出面乱码，比如输入 p "中国"，结果如图尝试修改 cmd 的字符集 chcp 65001，再输入中文，cmd 都崩掉退出了。虽然平时用 irb 比较少，但总感觉有骨在喉，想知道原因或解决办法，还主有了解着，不吝赐教。

Rails scaffold 执行报 Expected string default value for '--jbuilder'

OS: win10 x64 Ruby: 2.2.2 x86 rails: 5.0.0.1 jbuilder: 2.6.1

执行rails g scaffold Article name title content:text时，报

Expected string default value for '--jbuilder'; got true (boolean)
invoke  active_record
      create    db/migrate/20161213013344_create_articles.rb
      create    app/models/article.rb

      create      app/views/articles/index.html.erb
      create      app/views/articles/edit.html.erb
....

在网上没有找到相关的解释和解决办法，但在另一台 win7 x64，一样的环境就没有这个问题，求大神帮解释，看看可能把这个讨厌的东西干掉，先谢了！！！

ruby on rails 新建项目后，在创建 welcome/index 控制后，访问出错，报错内容如下：

新建项目： rails new blogV1.3 cd blogV1.3

新建控制： rails g controller welcome index

启动服务： rails s

访问 url： http://localhost:3000/welcome/index

查找了很多地方，有说把..\blogV1.3\app\views\layouts\application.html.erb

<!DOCTYPE html>
<html>
<head>
  <title>BlogV13</title>
  <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
  <%= csrf_meta_tags %>
</head>
<body>

<%= yield %>

</body>
</html>

中的 'data-turbolinks-track' => true 去除

请问有什么办法修复它，而不去除它吗？如果去除了，好像 js 不能正常工作了！

在网上找到几种解决办法，分享一下：

办法一：将 javascript_include_tag 'application'改成 javascript_include_tag 'defaults'，此方法已验证，暂时运行没问题，但在用到 delete 时，会失败。

办法二：安装 node.js，此方法试过了，没有成功，现在试其它版本的

办法三：在../app/assets/javascripts/application.js 中，删除 //= require turbolinks //= require_tree . 两行，此法可以解决，具体原理不是太明白，有明白的大神，还请指教一二，多谢！
