错误：在将 Angular CLI 与 ScrollMagic 和 GSAP 结合使用时无法解析“TweenMax”

Question

我正在尝试将 Scrollmagic 插件与 Angular CLI 集成。但是，我收到此错误：

./~/ScrollMagic/scrollmagic/minified/plugins/animation.gsap.min.js 未找到模块：错误：无法解析“TweenMax” '/Users/../project/node_modules/ScrollMagic/scrollmagic/minified/plugins'

我已经使用 npm 安装了 GSAP 和 scrollmagic 库：

npm install gsap
npm install scrollmagic

.angular-cli.json

"scripts": [
        "../node_modules/gsap/src/uncompressed/TweenMax.js",
        "../node_modules/scrollmagic/scrollmagic/minified/ScrollMagic.min.js",
        "../node_modules/scrollmagic/scrollmagic/minified/plugins/animation.gsap.min.js",
        "../node_modules/scrollmagic/scrollmagic/minified/plugins/debug.addIndicators.min.js"
      ],

组件

import { Component, OnInit } from '@angular/core';
import { TweenMax, TimelineMax } from "gsap";
import * as ScrollMagic from 'ScrollMagic';
import "ScrollMagic/scrollmagic/minified/plugins/debug.addIndicators.min.js";
import "ScrollMagic/scrollmagic/minified/plugins/animation.gsap.min.js";


@Component({
  selector: 'app-floating-butterfly',
  templateUrl: './floating-butterfly.component.html',
  styleUrls: ['./floating-butterfly.component.scss']
})
export class FloatingButterflyComponent implements OnInit {

  constructor() { }

  ngOnInit() {
    var controller = new ScrollMagic.Controller();
    var scene = new ScrollMagic.Scene({
      triggerElement: ".floating-butterfly"
    })
    .setTween(".floating-butterfly", 0.5, {backgroundColor: "green", scale: 2.5}) // trigger a TweenMax.to tween
    .addIndicators({name: "1 (duration: 0)"}) // add indicators (requires plugin)
    .addTo(controller);


  }
}

您应该“弹出”您的应用程序。这将使您可以访问 Webpack（不，您不能返回，因此请务必备份。）。

npm install gsap imports-loader scrollmagic --save

安装imports-loader很重要。当 webpack.config.js 添加到你的项目根目录时，重新安装应用程序npm install，因为有新的东西需要安装，然后把它放在你的 webpack 别名中：

  "alias": {
"TweenLite": path.resolve('node_modules', 'gsap/src/uncompressed/TweenLite.js'),
"TweenMax": path.resolve('node_modules', 'gsap/src/uncompressed/TweenMax.js'),
"TimelineLite": path.resolve('node_modules', 'gsap/src/uncompressed/TimelineLite.js'),
"TimelineMax": path.resolve('node_modules', 'gsap/src/uncompressed/TimelineMax.js'),
"ScrollMagic": path.resolve('node_modules', 'scrollmagic/scrollmagic/uncompressed/ScrollMagic.js'),
"animation.gsap": path.resolve('node_modules', 'scrollmagic/scrollmagic/uncompressed/plugins/animation.gsap.js'),
"debug.addIndicators": path.resolve('node_modules', 'scrollmagic/scrollmagic/uncompressed/plugins/debug.addIndicators.js'),},

将此添加到您的 Component.ts：

import 'imports-loader?define=>false!animation.gsap';
import ScrollMagic from 'ScrollMagic';
import 'scrollmagic/scrollmagic/uncompressed/plugins/debug.addIndicators';
import {TweenMax} from 'gsap/TweenMax';
import {TweenLite} from 'gsap/TweenLite';
import {ScrollToPlugin} from "gsap/ScrollToPlugin";

应该可以的
