javascript - 如何在 Systemjs builder 任务中包含 zone.js、reflect-metadata 等？

Question

我正在使用 system.js 和 systemjs builder 来创建 dist包含我的 angular2 应用程序的所有打包 javascript 文件的文件夹。

它工作得非常好，只是它不包含以下文件，这些文件当前静态包含在 index.html 中:

node_modules/zone.js/dist/zone.js

node_modules/reflect-metadata/Reflect.js

node_modules/systemjs/dist/system.src.js

node_modules/esri-system-js/dist/esriSystem.js

如何强制 systemjs builder 包含这些依赖项？

libs-bundle.js:

var SystemBuilder = require('systemjs-builder');
var builder = new SystemBuilder();
builder.loadConfig('./systemjs.config.js').then(function() {
  return builder.bundle(
    'app - [app/**/*]', // build app and remove the app code - this leaves only 3rd party dependencies
    'dist/libs-bundle.js'
  );
}).then(function() {
  console.log('library bundles built successfully!');
});

app-bundle.js

var SystemBuilder = require('systemjs-builder');
var builder = new SystemBuilder();
builder.loadConfig('./systemjs.config.js').then(function() {
  return builder.bundle(
    'app - dist/libs-bundle.js', // build the app only, exclude everything already included in dependencies
    'dist/app-bundle.js'
  );
}).then(function() {
  console.log('Application bundles built successfully!');
});

systemjs.config.js:

/**
 * System configuration for Angular 2 samples
 * Adjust as necessary for your application needs.
 */
(function(global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      app: 'dist',
      // angular bundles

    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        main: './main.js',
        defaultExtension: 'js'
      },
      rxjs: {

我会尝试在您的应用程序目录中为每个缺少的包执行 npm install

npm i zone.js
npm i reflect-js
npm i systemjs
npm i esri-system-js
