Question

今天早上我一直在将我的Angular RC 5应用程序更新到RC 6.在修复了代码中的一些问题之后我已经构建了代码，但是当应用程序正在被引导时我似乎有错误。（我不确定这一点，这只是我的怀疑）。

从研究中我发现它似乎是与webpack和@angular/upgrade相关的问题。（参见：https://github.com/angular/angular/issues/11249）。除此之外我没有找到很多信息，所以我希望有人遇到过类似的问题。

目前在控制台中我看到以下错误：

Uncaught SyntaxError: Unexpected token export
Uncaught TypeError: Cannot read property 'call' of undefined

当我浏览代码以查看失败的位置时，我注意到Uncaught SyntaxError: Unexpected token export错误来自index.js文件，index.js文件是@angular/upgrade文件1}}。在上面的链接中，提到@angular/upgrade没有指向正确的“UMD包”。说实话，我不确定这是什么意思，我不知道如何解决这个问题。

@angular/update index.js

更新：发现问题的来源

所以我一直在寻找解决问题的方法，然后我又回到了上面附带的链接。那里有一个标记的提交链接到同一个问题。（参见：https://github.com/angular/angular/commit/979657989bab4fb93faf6a207d30760faa9bd696）。一旦我查看了那里的更新，我就意识到必须要做什么。

问题是package.json包的@angular/upgrade指向错误的UMD文件。

你会注意到上面有一个"main": "bundles/core.umd.js"。

这应该更新为"main": "bundles/upgrade.umd.js"。

我猜这是包装本身的某种错误？可能它将在不久的将来得到修复。现在我不得不手动更改它以修复它。
