为依赖项/devDependencies 更新 Package.json 文件

"dependencies": {
    "@angular/animations": "^5.0.0",
    "@angular/common": "^5.0.0",
    "@angular/compiler": "^5.0.0",
    "@angular/core": "^5.0.0",

    "@angular/platform-browser-dynamic": "^5.0.0",
    "@angular/router": "^5.0.0",
    "core-js": "^2.4.1",
    "rxjs": "^5.5.2",
    "zone.js": "^0.8.14"

  }

运行 NPM 安装

npm install

【解决方案2】：

首先，控制台的错误在哪里？其次，您需要更改@angular/material 和@angular/cdk 的版本，只是：

npm install --save @angular/material@latest @angular/cdk@latest

或

npm install --save @angular/material@5.2 @angular/cdk@5.2

【讨论】：

@angular/material v2-beta 与 @angular v5 不兼容
