更新到Angular 6.0.1后,我收到以下错误ng serve:

Could not find module "@angular-devkit/build-angular" from "/home/Projects/myProjectName".
Error: Could not find module "@angular-devkit/build-angular" from "/home/Projects/myProjectName".
    at Object.resolve (/home/Projects/myProjectName/node_modules/@angular-devkit/core/node/resolve.js:141:11)
    at Observable.rxjs_1.Observable [as _subscribe] (/home/Projects/myProjectName/node_modules/@angular-devkit/architect/src/architect.js:132:40)

ng update说一切都井然有序.删除node_modules文件夹和全新npm install安装也没有帮助.

我的项目基于[ng2-admin(Angular4版本)].(https://github.com/akveo/ngx-admin)这是我的package.json dependecies:

 "dependencies": {
    "@angular/animations": "^6.0.1",
    "@angular/common": "^6.0.1",
    "@angular/compiler": "^6.0.1",
    "@angular/core": "^6.0.1",
    "@angular/forms": "^6.0.1",
    "@angular/http": "^6.0.1",

    "@angular/platform-server": "^6.0.1",
    "@angular/router": "^6.0.1",
    "@ng-bootstrap/ng-bootstrap": "1.0.0-alpha.26",
    "@ngx-translate/core": "^10.0.1",

    "amcharts3": "github:amcharts/amcharts3",
    "ammap3": "github:amcharts/ammap3",
    "angular-table": "^1.0.4",

    "angular2-datatable": "0.6.0",
    "animate.css": "3.5.2",
    "bootstrap": "4.0.0-alpha.6", …

在运行终端命令 ng server 或 ng serve 时，我遇到了这个问题：

发生未处理的异常：找不到模块“@angular-devkit/build-angular”
