我的Linux服务器上有两个用户：user1和user2
python3.8、pip、ansible-core、ansible-base&安装了jmespath。
我使用user1登录，上面的剧本运行良好
ansible-playbook test.yml
然而，当我使用user2登录并运行相同的程序时，我会得到以下错误
TASK[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=>｛在模板化字符串时出现模板错误：没有名为"json_query"的筛选器。字符串：{{jsondata|json_query(jmesquery(}｝"｝
注意：使用user1运行时，剧本运行良好。该错误仅在使用user2运行时出现。
我用user2设置的方式有什么问题吗？
以下是user2的详细信息

Defaulting to user installation because normal site-packages is not writeable

JmesPath安装如下：
$ sudo pip3.8 install jmespath

你能为这个问题提出一个解决方案吗？
因为您确实使用pip包ansible-core&ansible-base，您没有集合community.general，此筛选器是该集合的一部分。
您有多种选择：
- 当与有问题的用户一起登录时，安装丢失的集合：
ansible-galaxy collection install community.general - 安装完整的Ansible软件包：
pip uninstall ansible-core ansible-base pip install ansible - 使用选项
-p将集合重新安装到共享文件夹中ansible-galaxy collection install community.general -p /usr/share/ansible/collections
