Amazon web services Ansible add_主机不工作，它'；正在跳过主机

我使用Ansible创建一个新的EC2实例，并尝试在它上安装一些包。问题是我正在向一个主机组添加一个新主机，但在另一个播放中我看不到该主机组。当它到达“配置EC2实例”时，会显示：

播放[配置EC2实例]*************************************************************** 跳过：没有匹配的主机

代码如下：

从游戏中删除

meta:refresh_inventory

内存资源清册不需要它，它会导致Ansible根据文件和动态资源清册脚本刷新资源清册。它实际上会清除在上一步中创建的内存资源清册。

请提供ansible执行的全部输出。问题似乎出现在以前的任务中。Hi-techraf，我添加了ec2.tagged_实例的值和add_主机的输出。谢谢。请修复缩进，它会导致不必要的混乱（任务级别有一个游戏，但由于错误消息是正确的，所以它只是在问题中）。我知道缩进不好。stackoverflow编辑器不太擅长粘贴yaml代码。我将尝试修复它。谢谢。是的，你说得对。我不知道我昨晚在做什么。那是凌晨3点，我想我的想法不对。谢谢你的回答！
