升级到RC6后,出现如下错误:

zone.js:101 GET http://localhost/traceur 404 (Not Found)
zone.js:484 Unhandled Promise rejection: Error: XHR error (404 Not Found) loading http://localhost/traceur

zone.js:486 Error: Uncaught (in promise): Error: Error: XHR error (404 Not Found) loading http://localhost/traceur(…)
system.src.js:371 Assertion failed: loading or loaded

我知道如果没有代码就不容易解决问题,但也许有人有同样的错误并想通了。

现有的帖子没有解决我的问题

更新:系统.config.js:

// SystemJS configuration file, see links for more information
// https://github.com/systemjs/systemjs
// https://github.com/systemjs/systemjs/blob/master/docs/config-api.md

/***********************************************************************************************

"assets": "assets",
};

const packages: any = {

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

declare var System: any;

System.config({

// Apply the user's configuration.
System.config({ map, packages });

更新 2:我将 system.config.js 更改为以下内容:

//packages defines our app package
packages: {

},

}
});

现在我收到以下错误:

zone.js:101 GET http://localhost/vendor/@angular/common/bundles/common.umd.js/src/directives/core_directives 404 (Not Found)

最佳答案

下午好,我整天都有同样的问题。在查阅了几个不同的链接之后,我终于通过将 system.config.ts 更改为以下内容来启动并工作:

"use strict";
