Angular2升级到RC6，找不到traceur [英] Angular2 upgrade to RC6, traceur not found

问题描述

升级到RC6后，发生以下错误:

After upgrade to RC6, following errors occurs:

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
            at XMLHttpRequest.wrapFn [as _onreadystatechange] (http://localhost/vendor/zone.js/dist/zone.js:794:30)

            at Zone.runTask (http://localhost/vendor/zone.js/dist/zone.js:265:48)

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

我知道没有代码就很难解决问题，但是也许有人遇到相同的错误并弄清楚了.

I understand that without code there is not easy to solve problem, but maybe someone have same error and figured it out.

现有帖子无法解决我的问题

更新: system.config.js:

下午好， 我整天都遇到同样的问题.在咨询了几个不同的链接之后，我终于将其设置为系统，并将system.config.ts更改为以下内容:

Good afternoon, I had the same issue all day. After consulting several different links, I finally got it up and working by changing my system.config.ts to the following:
