Angular 2 systemjs

Question

我不太了解systemjs我在尝试通过angular

导入时遇到问题

效果很好

Import {UtilClass} from './shared/util.class';

我在另一个文件夹中有一个组件但是如果我尝试加载它

Import {UtilClass} from '../shared/util.class';

我有以下错误并在日志加载文件中验证我观察到的是当我使用＆＃34; ../" 时它没有放置扩展名js / util.class 404（未找到）

(function (global) {

var staticPath='src/';

var paths = {
    // paths serve as alias
    'npm:': 'https://unpkg.com/'
};

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

    'ts': 'npm:plugin-typescript@5.2.7/lib/plugin.js',
    'typescript': 'npm:typescript@2.2.1/lib/typescript.js',
};

// packages tells the System loader how to load when no filename and/or no extension
var packages = {

    'app': {
        main: '../..' + staticPath + '/main',
        defaultExtension: 'js',
        defaultJSExtensions: true
    }
    ,
    'rxjs': {
        defaultExtension: 'js'
    }
};

var config = {
    map: map,
    packages: packages,
    paths: paths
};

System.config(config);
})(this);

当路线相对时会发生此错误，我想有更好的方法可以纠正它。

var packages = {
'app': {
    main: '../..' + staticPath + '/main',
    defaultExtension: 'js',
    defaultJSExtensions: true
}
,
'rxjs': {
    defaultExtension: 'js'
}
};
//I added this and works
packages['./../..'+staticPath+'/']={main:'main',defaultExtension: 'js'}
