Question

我在加载angular2-modal弹出窗口时遇到了一些问题。获得此异常“意外的令牌＆lt; - 缺少文件lib / angular2-modal / plugins / bootstrap.js” 在我尝试启动应用程序时编译后，它正在尝试评估路径中的文件

“Evaluating http://localhost:49928/lib/angular2-modal/plugins/bootstrap.js”

但是在指定的位置没有这样的文件，因此应用程序崩溃了。在lib / angular2-modal / plugins /文件夹下，bootstrap.js文件不存在。但为什么在这里寻找这个文件？

Error: SyntaxError: Unexpected token <

SystemJS.Config.js文件如下

为什么我收到此错误的任何想法？为什么要在angular2-modal文件夹下查找plugins / bootstrap.js文件？

我已经解决了这个问题。

我已根据下面更改了我的systemjs.config.js文件，现在它可以正常工作了。

 (function (global) {
var ngVer = '@4.1.1'; // lock in the angular package version; do not let it float to current!
    var routerVer = '@4.1.1'; // lock router version
    var formsVer = '@4.1.1'; // lock forms version


    var angular2ModalVer = '@2.0.2';
    var plugin = 'bootstrap'; // js-native / vex

    global.angular2ModalVer = angular2ModalVer;


    //map tells the System loader where to look for things
    var map = {
        'app': 'app',

        '@angular': 'https://unpkg.com/@angular', // sufficient if we didn't pin the version
        '@angular/router': 'https://unpkg.com/@angular/router' + routerVer,
        '@angular/forms': 'https://unpkg.com/@angular/forms' + formsVer,

        'angular2-in-memory-web-api': 'https://unpkg.com/angular2-in-memory-web-api', // get latest

        'typescript': 'https://unpkg.com/typescript@1.9.0-dev.20160409/lib/typescript.js',


        'angular2-modal': 'https://unpkg.com/angular2-modal' + angular2ModalVer
    };

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

    // Add map entries for each angular package
    // only because we're pinning the version with `ngVer`.
    ngPackageNames.forEach(function (pkgName) {
        map['@angular/' + pkgName] = 'https://npmcdn.com/@angular/' + pkgName + ngVer;
    });

    // Add package entries for angular packages
    ngPackageNames.concat(['forms', 'router', 'router-deprecated']).forEach(function (pkgName) {

        // Bundled (~40 requests):
        packages['@angular/' + pkgName] = { main: '/bundles/' + pkgName + '.umd.js', defaultExtension: 'js' };

        // Individual files (~300 requests):
        //packages['@angular/'+pkgName] = { main: 'index.js', defaultExtension: 'js' };
    });

    var config = {
        // DEMO ONLY! REAL CODE SHOULD NOT TRANSPILE IN THE BROWSER
        transpiler: 'ts',
        typescriptOptions: {
            tsconfig: true

    System.config(config);

})(this);
