ng 更新后，ng serve 失败并抛出错误

编程问答 2022-05-24

问题描述

使用 ng update @angular/cli @angular/core 命令将 angular 6 应用程序更新为 angular 11 后，ng serve 抛出以下错误。

我尝试了以下选项

    • npm uninstall @angular-devkit/build-angular
    • npm install @angular-devkit/build-angular

  2. 删除 node_modules 并运行 npm install

仍然显示相同的错误

**

发生未处理的异常：找不到实现 builder @angular-builders/custom-webpack:browser
