模板化字符串时出现错误模板错误：没有名为“json_query”的过滤器

Question

有了这本剧本

---
- name: ReadJsonfile
  hosts: localhost
  tasks:
    
    - name: Display the JSON file content
      shell: "cat config.json"
      register: result

    - name: save the Json data to a Variable as a Fact
      set_fact:
        jsondata: "{{ result.stdout | from_json }}"

    - name: setDomainName
      set_fact:
        domain_name: "{{ jsondata | json_query(jmesquery) }}"
      vars:
        jmesquery: '[].domain[].name'

我的 Linux 服务器上有两个用户：user1和user2

python3.8、pip、ansible-core、ansible-base&jmespath已安装。

我登录user1 ，上面的剧本运行良好

ansible-playbook test.yml

但是，当我登录并user2运行相同的命令时，我收到以下错误

任务 [setDomainName] ************************************************** ********************************************** 2022 年 3 月 21 日星期一 01： 16:40 -0500 (0:00:00.140) 0:00:04.221 ********** 致命：[localhost]：失败！=> {“msg”：“模板化字符串时出现模板错误：没有名为“json_query”的过滤器..字符串：{{ jsondata | json_query(jmesquery) }}”}

注意：user1与剧本一起运行时效果很好。该错误是在仅运行时出现的user2。

我的设置方式有问题吗user2？

以下是详细信息user2

您能提出解决该问题的建议吗？

Answer 1

因为您确实使用 pip 包ansible-core&安装了 Ansible ansible-base，所以您没有community.general该过滤器所属的集合。

您有多种选择：

1. 当使用有问题的用户登录时，安装缺少的集合：

   ansible-galaxy collection install community.general
   

2. 安装完整的 Ansible 软件包：

   pip uninstall ansible-core ansible-base
   pip install ansible
   

3. 使用选项重新安装共享文件夹中的集合-p

   ansible-galaxy collection install community.general \
       -p /usr/share/ansible/collections
