Question

我正在将应用程序从Angular 5迁移到Angular6。目前，我相信我已经解决了大多数问题，并且在使用ng serve或ng build main进行构建时，它的构建符合预期。但是，当以ng build --prod main进行构建时，出现以下错误

ERROR in : Error: Illegal State: literal maps should have been converted into functions

我对此有两个疑问

此错误实际上是什么意思
我如何找到它并对其进行纠正

Answer 1

从angular 6.0迁移到7.0后，我启用了ivy编译器，并且遇到了相同的错误。禁用常春藤选项，AOT构建将再次起作用。
