ERROR in ./src/main.ts Module build Failed: Error: AotPlugin was detected but it was an instance of the wrong class. This likely means you have several @ngtools/webpack packages installed. You can check this with `npm ls @ngtools/webpack`,and then remove the extra copies. at Object.ngcLoader (D:\testingapp\node_modules\@ngtools\webpack\src\loader.js:358:19) @ multi webpack-dev-server/client?http://localhost:4200 ./src/main.ts
npm ls @ngtools/webpack
testingapp@0.0.0 D:\testingapp +-- @angular/cli@1.2.6 | `-- @ngtools/webpack@1.5.5 `-- angular-cli@1.0.0-beta.28.3 `-- @ngtools/webpack@1.5.1

运行ng弹出并尝试运行我的业力测试后,这个问题出现了.
原文链接：https://www.f2er.com/angularjs/141444.html即使我不认为这是一个最佳解决方案,我通过以下方式解决了这个问题：
>删除@ ngtools / webpack
$npm remove –save @ ngtools / webpack
>在我的webpack.config.js中要求@ ngtools / webpack是@ angular / cli的子依赖项
// webpack.config.js
//
// Other require statements
const { AotPlugin } =
require('./node_modules/@angular/cli/node_modules/@ngtools/webpack');

*更改装载机

module.exports = {

"module": {
"rules": {

{
"test": /\.ts$/,/* REMOVE: "loader": "@ngtools/webpack",*/
"loader":

}
