我如何在angular2中导入@ types/3

Question

经过几个小时的搜索和测试.我终于放弃了.我正在使用Angular2和webpack,我尝试在angular2应用程序中使用three.js.我已经安装了npm包@type/three

sudo npm install @types/three --save

我已经以多种方式编辑了我的tsconfig.json.我甚至尝试在我的polyfills.browser.ts中添加导入"三/三".但我一直在努力解决模块错误.也许我的tsconfig.json有问题如下

    {
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5",
        "outDir": "dist",
        "rootDir": ".",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "moduleResolution": "node",
        "typeRoots": [
            "./node_modules/@types"
        ],
        "types": [
            "core-js",
            "node",
            "three"
        ]
    },
    "exclude": [
        "node_modules"
    ],
    "awesomeTypescriptLoaderOptions": {
        "useWebpackText": true
    },
    "compileOnSave": false,
    "buildOnSave": false,
    "atom": {
        "rewriteTsconfig": false
    }
}

我在我的Component中至少尝试了以下语法

import {THREE} from "@types/three";
import {THREE} from "three";
import "@types/three";
import "three";
import * as _ from "@types/three";
import * as _ from "three";

实际上我真的不明白所有那些tsconfig,webpackconfig是如何工作的,所以当我尝试实现这个@ types/module时我不知道我在做什么.任何帮助将不胜感激,谢谢!

您还必须安装three.js包.

npm install three --save
npm install @types/three --save

测试组件:

import { Component, AfterViewInit } from '@angular/core';
import * as THREE from 'three';

@Component({
  selector: 'my-app',
  template: `<h1>Hello {{name}}</h1>`,
})
export class AppComponent implements AfterViewInit {
  name = 'Angular';
  scene: any;
  camera: any;
  renderer: any;
  geometry: any;
  material: any;
  mesh: any;

  ngAfterViewInit() {
    this.init();
    this.animate();
  }

  init() {
    this.scene = new THREE.Scene();

    this.camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 1, 10000);
    this.camera.position.z = 1000;

    this.geometry = new THREE.BoxGeometry(200, 200, 200);
    this.material = new THREE.MeshBasicMaterial({ color: 0xff0000, wireframe: true });

    this.mesh = new THREE.Mesh(this.geometry, this.material);
    this.scene.add(this.mesh);

    this.renderer = new THREE.WebGLRenderer();
    this.renderer.setSize(window.innerWidth, window.innerHeight);

    document.body.appendChild(this.renderer.domElement);

  }

  animate() {
    requestAnimationFrame(this.animate);
    this.mesh.rotation.x += 0.01;
    this.mesh.rotation.y += 0.02;
    this.renderer.render(this.scene, this.camera);
  }
}

在systemjs.config.js中添加地图

'three': 'npm:/three/build/three.min.js',
