ruby-on-rails - 创建新的 RailsApp 时 Rails_uis 抛出错误

Question

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

任何想法出了什么问题..突然发生..

包.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，解决问题，

在 babel.config.js 中注释掉 //corejs: 3
