创建新的 ruby 2.6 / rails6 应用程序并搭建脚手架后，destroy 弹出窗口不起作用。

知道哪里出了问题吗？突然发生。

package.json

{
  "name": "untitled1",
  "private": true,
  "dependencies": {
  "@rails/actioncable": "^6.0.0-alpha",
  "@rails/activestorage": "^6.0.0-alpha",
  "@rails/ujs": "^6.0.0-alpha",
  "@rails/webpacker": "^4.0.6",
  "turbolinks": "^5.2.0",
},
  "version": "0.1.0",
  "devDependencies": {
  "webpack-dev-server": "^3.5.1"
}

github.com/rails/webpacker/issues/2109, 解决了这个问题,

在 babel.config.js 中注释掉 //corejs: 3,

希望这个 bug 能尽快得到解决。

对于任何像我一样愚蠢的人，这个问答是我唯一可能的线索（这不会给你任何结果）——我遇到的 Rails 未定义问题是因为我的 javascript_include_tag 丢失了。简而言之，请确保您有：

<!-- app/views/layouts/application.html -->
<!-- turbolinks optional -->
<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>
