好吧，所以我从主模板调用嵌套堆栈。我以为我已经想出如何正确导出值并在嵌套堆栈之间导入。我意识到很多我的命名约定格式都没有达到标准，我本周才开始学习CloudFormation Scripting。
每当我尝试创建这个堆栈时，它们都会创建，直到我进入“公共路线”，此时我得到一个：
Template format error: Unresolved resource dependencies [InternetGatewayStackname] in the Resources block of the template
据我所知，我做的公共路由与Vpc堆栈完全相同，这有效。出于某种原因，我无法让公共路线发挥作用。
主要筹码：

您的资源名为InternetGatewayStackName。
但在您的PublicRoute资源中，您使用的是以下内容：
"Fn::Sub" : "${InternetGatewayStackname}"
请注意，sub中的大小写与资源名称中的大小写不匹配。
