出现了未处理的异常：找不到@angular-devkit/build-angular:dev-server构建器的实现。
这个问题已经在这里有了答案：
我尝试安装ngb-tabset，但在angular-core上遇到了一些错误，因此我运行了：
npm install -S @angular/material @angular/cdk @angular/animations npm uninstall @angular/core npm install -S @angular/core
但是然后我得到了一些其他的错误...然后我做了 npm update，然后又出现了几个错误。我做了：
rm -rf node_modules npm install
然后我开始收到下面的错误。
未处理的异常：找不到 @angular-devkit/build-angular:dev-server 构建器的实现
请参阅“/tmp/ng-2tgkqg/angular-errors.log”了解更多详细信息。
我尝试做 -
npm install --save-dev @angular-devkit/build-angular
但没有用。
我的 package.json 是 -

我也遇到了相同的问题，我是这样解决的！
1- npm rm -rf node_modules 2- npm install --save-dev @angular/cli@latest 3- npm uninstall @angular-devkit/build-angular 4- npm i --save-dev @angular-devkit/build-angular@latest 5- npm install -g rxjs-tslint 6- npm install --save-dev typescript@7- ng update 8- ng update @angular/cli @angular/core --allow-dirty --force 9- ng build
它工作的非常好！
详情请参考这里。
对我有效:
根据@lak-coder在：https://github.com/angular/angular-cli/issues/14546
运行
npm uninstall @angular-devkit/build-angular
然后
npm install --save-dev @angular-devkit/build-angular
