【问题描述】：
我尝试在this 之后更新 Angular CLI，但现在我无法运行我的应用程序。当我尝试运行命令ng serve 时，它给了我这个错误：
Could not find the implementation for builder @angular-devkit/build-angular:dev-server
Error: Could not find the implementation for builder @angular-devkit/build-angular:dev-server

at startup (internal/bootstrap/node.js:283:19)
at bootstrapNodeJSCore (internal/bootstrap/node.js:743:3)
我已经尝试了所有我能找到的东西。
- 我尝试使用命令
npm install --save-dev @angular-devkit/build-angular手动安装devkit - 我尝试运行命令
npm i --only=dev - 我尝试运行命令
：
npm install
ng update
npm update
- 删除了
node_modules文件夹和package-lock.json文件并再次运行所有命令。
没有任何效果。运行ng v 给了我这个：
