Angular CLI 和 Angular Material(原理图)错误 : Collection "@angular/material" cannot be resolved

Question

我正在尝试使用 this page. 上显示的 Angular 模式当我尝试在项目根目录下的终端中使用以下命令时 ng generate @angular/material:material-nav --name name-of-new-nav，出现以下错误红色的，

Collection "@angular/material" cannot be resolved. Error: Collection "@angular/material" cannot be resolved. at NodeModulesEngineHost._resolveCollectionPath (/Users/jeremypeters/MEGA/development/learning/angular/material-learn/node_modules/@angular-devkit/schematics/tools/node-module-engine-host.js:88:15) at NodeModulesEngineHost.createCollectionDescription (/Users/jeremypeters/MEGA/development/learning/angular/material-learn/node_modules/@angular-devkit/schematics/tools/file-system-engine-host-base.js:106:27) at SchematicEngine._createCollectionDescription (/Users/jeremypeters/MEGA/development/learning/angular/material-learn/node_modules/@angular-devkit/schematics/src/engine/engine.js:78:40) at SchematicEngine.createCollection (/Users/jeremypeters/MEGA/development/learning/angular/material-learn/node_modules/@angular-devkit/schematics/src/engine/engine.js:71:43) at Object.getCollection (/Users/jeremypeters/MEGA/development/learning/angular/material-learn/node_modules/@angular/cli/utilities/schematics.js:28:31) at GenerateCommand.getOptions (/Users/jeremypeters/MEGA/development/learning/angular/material-learn/node_modules/@angular/cli/models/schematic-command.js:193:41) at GenerateCommand.

好像坏了，临时解决方案，使用以下版本

ng add @angular/material@6.2.1
