Question

我有我的第一本剧本，但它失败了。我认为这是一个语法错误，但由于我不是编码器，我不知道为什么YAML会失败？是否与间距有关？

这就是我所拥有的：

---
- name: Update all packages to the latest version
    become: true
    apt:
      update_cache: yes       
      upgrade: dist

- name: Remove useless packages from the cache
    apt:
      autoclean: yes

- name: Remove dependencies that are no longer required
    apt:
      autoremove: yes

ERROR! Syntax Error while loading YAML.


The error appears to have been in '/home/pi/playbooks/update-apt.yml': line 3, column 11, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

- name: Update all packages to the latest version
    become: true
          ^ here

首先：这不是剧本，因为它不包含剧本（必须包含hosts声明），但是任务。

其次：你的缩进被严重破坏 - 在YAML中保持声明正确对齐是很关键的（也就是说，你看到的错误不是YAML语法错误，而是由正确写入的不正确数据导致的Ansible错误YAML文件）。

如果你想在本地运行它，它应该或多或少看起来像这样：

---
- hosts: localhost
  connection: local
  tasks:
    - name: Update all packages to the latest version
      become: true
      apt:
        update_cache: yes       
        upgrade: dist
        autoclean: yes
        autoremove: yes
