导入 MdSelectModule 导致 angular 构建失败

Question

当我尝试导入时 MdSelectModule angular 我遇到很多构建错误：

import {MdSelectModule} from '@angular/material';

这里是package.json的内容：

 {
  "name": "sbmclient",
  "version": "0.0.0",
  "license": "MIT",
  "angular-cli": {},
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "test": "ng test",
    "pree2e": "webdriver-manager update --standalone false --gecko false",
    "e2e": "protractor"
  },
  "private": true,

    "ts-node": "1.2.1",
    "tslint": "^4.3.0",
    "typescript": "^2.0.10"
  }
}

构建结果报告了很多这样的错误：

    ERROR in D:/.../node_modules/@angular/material/typings/core/overlay/scroll/scrollable.d.ts (1,49): Mo
dule '"D:/.../node_modules/@angular/core/index"' has no exported member 'Renderer2'.

ERROR in D:/.../node_modules/@angular/material/typings/core/overlay/scroll/scroll-dispatcher.d.ts (10

ERROR in D:/.../node_modules/@angular/material/typings/core/overlay/overlay-directives.d.ts (1,78): M
odule '"D:/.../node_modules/@angular/core/index"' has no exported member 'Renderer2'.

我的包文件有问题吗？

Answer 1

基本上问题是 Renderer2 只存在于 Angular 4.0.0 rc.1 而您使用的是 Angular 4.0.0 beta 3.

另外，有人提到 here 因为版本 Angular Material 2 (beta 3) 它依赖于 Angular 4.0.0 而你使用的是 Material2 beta 5 与 Angular 4.0.0 beta 3。所以它可能不起作用，因为正如您在 Angular 的 CHANGELOG（上面的 link）中看到的那样，Renderer2在rc.1版本之前被称为RendererV2。

解决方法：更新@angular/*packages到最新（包括@angular/compiler-cli~这个真的很老~ ).
