ng build --prod 问题 [英] ng build --prod issue

问题描述

我正在使用最新版本的 @angular/cli 并且在我的 Angular2 应用程序中有一个奇怪的错误.

I'm working with the latest version of @angular/cli and have a weird error in me Angular2 App.

进行 ng build --pro 后，bundle 无法正常工作，我可以在控制台中看到此错误:

After make a ng build --pro the bundle doesn't work properly, I can see this error in the console:

例外:无法设置只有 getter 的 # 的属性值

EXCEPTION: Cannot set property value of # which has only a getter

但是，进行无参数构建，工作正常，有什么想法吗?

But,making a no parameters build, works fine,any idea?

这是我的 package.json 的一大块

通过在 ng build 命令期间添加 --aot=false 关闭 aot 可以解决问题.

Turning aot off by adding --aot=false during the ng build command it fixes the problem.

此外，我已将打字稿版本提高到 2.1.6.

Also I've raised the typescript version to 2.1.6.
