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

通过此剧本，

---
- 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、<代码>ansible-core、ansible-base & jmespath 已安装。

我使用 user1 登录，上面的剧本运行良好

ansible-playbook test.yml

但是，当我使用 user2 登录并运行相同的内容时，我得到下面的错误

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：{{ json数据 | json_query(jmesquery) }}"}

注意： 当使用 user1 运行时，playbook 工作正常。错误仅在使用 user2 运行时出现。

是我使用 user2 设置的方式有问题吗？

：您能否建议解决该问题的方法？

Answer 1

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

您有多个选择：

1. 当使用有问题的用户登录时，安装缺少的集合：

   ansible-galaxy集合安装community.general
   

2. 安装完整的 Ansible 软件包：

   pip uninstall ansible-core ansible-base
   pip 安装 ansible
   

3. 使用选项 -p 在共享文件夹中重新安装集合

   ansible-galaxy集合安装community.general \
       -p /usr/share/ansible/集合
