【问题描述】：
我正在使用 typescript 和 angular2，我想在我的项目中使用 SockJS。我跑：npm install sockjs-client。现在我想在systemjs.config.js 中添加node_modules/sockjs-client 的映射。这是文件现在的样子：
/**
* 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: 'app',
// angular bundles
'@angular/core': 'npm:@angular/core/bundles/core.umd.js',
'@angular/common': 'npm:@angular/common/bundles/common.umd.js',
'@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
'@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
'@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
'@angular/http': 'npm:@angular/http/bundles/http.umd.js',
'@angular/router': 'npm:@angular/router/bundles/router.umd.js',
'@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
// other libraries
'rxjs': 'npm:rxjs',
'angular2-in-memory-web-api': 'npm:angular2-in-memory-web-api',
'sockjs-client': 'npm:sockjs-client',
'stompjs': 'npm:stompjs/lib/stomp.min.js'
},
// packages tells the System loader how to load when no filename and/or no extension
packages: {
app: {
main: './main.js',
defaultExtension: 'js'
},
rxjs: {
defaultExtension: 'js'
},
'angular2-in-memory-web-api': {
main: './index.js',
defaultExtension: 'js'
}
}
});
})(this);
我在浏览器中有以下异常：
localhost/:16 Error: Error: XHR error (404 Not Found) loading http://localhost:8080/node_modules/sockjs-client(…)
sockjs-client 库的正确 systemjs 映射是什么？
