问题描述

我在运行流程时遇到这些错误，但根本不确定为什么:

I'm getting these errors when I run flow but not sure at all why:

推荐答案

这是因为您启用了类型优先的体系结构，这意味着必须在模块边界处显式键入才能导出它.

This is because you have the types first architecture enabled which means that at module boundaries must be explicitly typed before you can export it.

您可以在此处了解更多信息什么是类型优先"?流架构?
