Question

当我尝试导入MdSelectModule角度时，我面临很多构建错误：

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

以下是package.json的内容：

 {
  "name": "sbmclient",
  "version": "0.0.0",
  "license": "MIT",
  "angular-cli": {},
  "scripts": {
    "ng": "ng",

    "pree2e": "webdriver-manager update --standalone false --gecko false",
    "e2e": "protractor"
  },

    "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'.

我的包裹文件有什么问题吗？

Answer 1

基本上问题是 Renderer2 仅存在于Angular 4.0.0 rc.1，您使用的是Angular 4.0.0 beta 3 。

此外，它提到了here，因为版本Angular Material 2 (beta 3)依赖于Angular 4.0.0并且你使用 Material2 beta 5 Angular 4.0.0 beta 3 。因此，它可能无效，因为您可以在Angular的 CHANGELOG （上面的链接）中看到， Renderer2 之前被称为 RendererV2 rc.1版本）。

解决方案：将@angular/* 个套餐更新到最新版本（包括@angular/compiler-cli〜这真的很旧〜）。
