将TypeScript目标更新为ES6时，aurelia bundler出现JS_Parse_Error

Question

我遇到了一个问题，似乎阻止了我使用async/await(甚至yield/generators)。

我开始用aurelia骨架打字&asp5(aspnetcore)。默认目标设置为es5。我想在我的TypeScript代码中使用async/await，所以我正在尝试将目标更新为es6。

在将tsconfig.json从es5更新到es6之后，发生了一些事情。首先，有很多重复错误(我设法解决了)。剩下的问题是我从aurelia bundler中的依赖关系中得到的错误。

注意：假设这是堆栈跟踪中文件路径的根路径：C:\My\My。App\src\My。应用程序。Web\node_modules\aurelia bundler\node_modules\systemjs-builder

有人知道为什么会发生这种情况吗？我将尝试更新所需的任何其他信息。

非常感谢。

更新1

该项目构建步骤的一部分是使用aurelia bundler创建将被应用程序引用的javascript捆绑包。这大部分是从aurelia骨架中未被触及的。知道line 13中的代码是什么是不可能的。

我尝试将节点从v4升级到v6，但错误仍然存在。我回到v4.4.4。

我还尝试从config.js中更新系统js配置，但没有成功。

以下是我当前的配置：

您正在运行哪个版本的Node.js？如果您使用的是节点v4，请尝试节点v6(如果可以的话)。

您收到的消息表明存在某种JavaScript解析错误，很可能是由运行时环境中不完整的ES6支持引起的。因此，升级可能会使问题消失。如果没有，代码中第13行第8列的内容是什么？(如错误消息所示)
