当我尝试更新为angular2发布候选版本时，我有些困难

Question

  

我的系统js配置看起来像

/**

(function(global) {

    // map tells the System loader where to look for things
    var map = {
        'app':                        'app', // 'dist',
        'rxjs':                       'node_modules/rxjs',
        'angular2-in-memory-web-api': 'node_modules/angular2-in-memory-web-api',
        '@angular':                   'node_modules/@angular',
        'moment':                     'node_modules/moment/moment.js',
    };

    // packages tells the System loader how to load when no filename and/or no extension
    var packages = {
        'app':                        { main: 'main.js',  defaultExtension: 'js' },
        'rxjs':                       { defaultExtension: 'js' },
        'angular2-in-memory-web-api': { defaultExtension: 'js' },
    };

    var packageNames = [
        '@angular/common',
        '@angular/compiler',
        '@angular/core',
        '@angular/http',
        '@angular/platform-browser',
        '@angular/platform-browser-dynamic',
        '@angular/router',
        '@angular/router-deprecated',
        '@angular/testing',
        '@angular/upgrade',
    ];

    // add package entries for angular packages in the form '@angular/common': { main: 'index.js', defaultExtension: 'js' }
    packageNames.forEach(function(pkgName) {
        packages[pkgName] = { main: 'index.js', defaultExtension: 'js' };
    });

    var config = {
        map: map,
        packages: packages,
        paths: {
            underscore: './node_modules/underscore/underscore.js'
        }
    }

    // filterSystemConfig - index.html's chance to modify config before we register it.
    if (global.filterSystemConfig) { global.filterSystemConfig(config); }

    System.config(config);

})(this);

  

我不明白为什么他会尝试从中加载角度库   / angular2 / core而不是来自/ node_modules / @ angular / comon？   任何人都可以解释systemJs如何加载文件？

Answer 1

您需要将导入更改为

import { ... } from '@angular/core'

Answer 2

我发现问题是因为我使用ng-2 bootstrap并且如果有人想要更新ng-2 bootstrap到angular 2 relese版本只更换来自min.js的所有导入替换angular2 @angular，对于angular2 / animation_builder，需要替换@ angular / platform_browser
