Python 类型错误：'；非类型'；对象在ansible中不可下标

这是我的剧本。yml呼叫角色

playbook.yml

我的角色aws vpc包含任务、vars目录

任务中的main.yml

变量中的main.yml

---

但在执行ansible playbook playbook.yml时，会显示以下错误：

为什么会发生，如何解决

---

这里vpc创建成功，但子网出现问题。为什么？

最后，我找到了答案，希望与大家分享

任务中的main.yml

---

问题在于空间。因此请注意这些问题。

您是否可以将

区域

参数添加到

ec2\u vpc\u子网

模块中，因为默认情况下它使用us-east-1`但您的vpc位于

us-west-2
