Question

我使用angular cli 6.2.4项目并创建了angular6项目。

我想使用environment / configuration选项为dev和prod创建特定的配置。

我认为我需要执行ng build --configuration=production

但这给了我以下错误：

ERROR in: Encountered undefined provider! Usually, this means you have a circular dependency. This might be caused by using 'barrel' index.ts files.

不带任何参数运行ng build不会给我带来任何问题。

在src/environments中，除了已经存在的environment.dev.ts之外，我还创建了一个environment.prod.ts。

这是我完整的angular.json文件：

我应该从一开始就听过@ Suresh-Kumar-Ariya，但是这个话题让我有些困惑。

@ user184994第5次阅读这篇文章后也对我有所帮助，我真的应该检查我的提供者，因为这是仅在使用AOT时才发现的问题。

所以无论如何我都使用Document作为提供者，我读了一些我需要使用它的地方才能使用document，这是错误的。删除它可以解决问题

谢谢
