如何在 ansible 中使用 {{ item }}？

Question

我正在尝试从 ansible 文档复制第一个 with_item 示例，但我遇到了这个错误：

fatal: [user@my-vm]: FAILED! => {"msg": "The task includes an option with an undefined variable.
The error was: 'item' is undefined\n\nThe error appears to be in 'path/ansible/playbooks/android-dev.yml': line 4,
column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\n
The offending line appears to be:\n\n  tasks:\n    - name: Debugging with items\n      ^ here\n"}

我的代码是：

- hosts: test
  tasks:
    - name: Debugging with items
      debug:
        msg: "An item: {{ item }}"
        with_items:
          - 1
          - 2
          - 3

我正在按照此页面的第一个示例来构建任务：https://docs.ansible.com/ansible/latest/plugins/lookup/items.html

我现在已经开始使用ansible了，这可能是一个很容易解决的问题，但是我真的在网上找不到任何解决方案

缩进错误。修复它

- hosts: test
  tasks:
    - name: Debugging with items
      debug:
        msg: "An item: {{ item }}"
      loop:
        - 1
        - 2
        - 3

使用loop 代替with_items。
