我正在尝试在刚启动的angular2 rc5项目中导入angular2 cookie模块。
我用npm
安装了模块npm install angular2-cookie
编辑了我的angular-cli-build.js文件：
module.exports = function(defaults) {
return new Angular2App(defaults, {
vendorNpmFiles: [
'systemjs/dist/system-polyfills.js',
'systemjs/dist/system.src.js',
'zone.js/dist/**/*.+(js|js.map)',
'es6-shim/es6-shim.js',
'reflect-metadata/**/*.+(ts|js|js.map)',
'rxjs/**/*.+(js|js.map)',
'@angular/**/*.+(js|js.map)',
'materialize-css/bin/materialize.css',
'materialize-css/bin/materialize.js',
'socket.io-client/socket.io.js',
'angular2-cookie/**/*.+(ts|js|js.map)'
]
});
};
运行构建
angular2-cookie文件夹在我的dist / vendor文件夹中创建
我的system-config.ts看起来像这样
"use strict";

const cliSystemConfigPackages: any = {};
barrels.forEach((barrelName: string) => {
cliSystemConfigPackages[barrelName] = { main: 'index' };
});

declare var System: any;
// Apply the CLI SystemJS configuration.
System.config({
map: {

'rxjs': 'vendor/rxjs',
'main': 'main.js',
"socket.io-client": "node_modules/socket.io-client/socket.io.js",

"socket.io-client": {"defaultExtension": "js"},
'angular2-cookie' : { defaultExtension: 'js',main: 'core.js'}
});
// Apply the user's configuration.
System.config({ map, packages });
我设法导入它并在我的组件文件中添加一些代码
import {CookieService} from 'angular2-cookie/core';
但由于某些原因，当我尝试为应用程序提供服务时，无法加载以下错误

看起来像angular2 cookie文件夹无法访问（或未正确提供），但无法找到原因。

您需要在这些对象中设置地图和包。不要修改这些行以下的任何内容。
/** Map relative paths to URLs. */
const map: any = {
'angular2-cookie': 'vendor/angular2-cookie'
};
/** User packages configuration. */
const packages: any = {
'angular2-cookie': {main: 'core.js', defaultExtension: 'js'},
};
请注意，目前angular2-cookie不适用于rc6，但新版本正在进行中。我想它会在今天或明天发布。

您在配置文件"angular2-cookie": 'vendor/angular2-cookie'中进行了映射，
所以你需要拨打import {CookieService} from 'angular2-cookie';
应该可以使用，否则请检查此文件夹/vendor/angular2-cookie/，并检查是否存在core.js文件，您在System.config 'angular2-cookie' : { defaultExtension: 'js',main: 'core.js'}中为此模块设置了默认文件。
