Angular 5 丑陋构建返回错误

Question

我将我的SPA从Angular 4更新到Angular 5，其中包含所有依赖项。到目前为止效果很好。开发和生产构建工作得很好。没有错误或警告。

当我使用--prod标志构建 SPA 时，angular-cli会使构建变得丑陋。没有来自angular-cli的错误。但是当我在浏览器中打开SPA时，我遇到了错误，没有任何反应。页面根本不加载(仅加载微调器(。

Uncaught Error: Unexpected value 'Ie' imported by the module 't'. Please add a @NgModule annotation.

如何调试正在发生/出错的情况？

Answer 1

由于 @Kevin RED，我通过以下简单的解决方案解决了这个问题。

以前：

"scripts": {
    "prod": "ng build --prod --aot false"
}

后：

"scripts": {
    "prod": "ng build --prod --aot false --build-optimizer=false"
}

我现在不确定build-optimizer的功能是什么(npmjs-build-optimizer(，但是如果我将其设置为 true ，则会收到错误。设置false，它可以工作。
