ansible报错解决：Failed to import the required Python library (netaddr)

问题情况

今天我在做实验的时候出现了一个问题，以下是我的playbook，这个playbook是验证变量ip_address是否是一个合法的IP地址，并打印相应的信息的一个剧本

[root@localhost ansible]# vim test6.yml 
- hosts: testvars:ip_address: "192.168.2455.1"tasks:- name: "判断{{ip_address}}是否为合法ip"debug:msg: "{{ ip_address | ipaddr}}"
# 执行结果
[root@localhost ansible]# ansible-playbook test6.yml PLAY [test] *************************************************************************************************************************TASK [Gathering Facts] **************************************************************************************************************
ok: [192.168.200.20]TASK [判断192.168.2455.1是否为合法ip] *********************************************************************************************
fatal: [192.168.200.20]: FAILED! => {"msg": "template error while templating string: Could not load \"ipaddr\": 'Invalid plugin FQCN (ansible.netcommon.ipaddr): unable to locate collection ansible.netcommon'. String: {{ ip_address | ipaddr}}. Could not load \"ipaddr\": 'Invalid plugin FQCN (ansible.netcommon.ipaddr): unable to locate collection ansible.netcommon'"}PLAY RECAP **************************************************************************************************************************

这里报错没有识别ipaddr这个集合，并告诉你没有安装ansible.netcommon.ipaddr集合，这时候我们安装集合就好了对吧

# 安装集合
[root@localhost ansible]# ansible-galaxy collection install /root/ansible-netcommon-6.1.1.tar.gz

# 查看集合
[root@localhost ansible]# ansible-galaxy collection list
# 这里是我自己设置的集合路径，显示已经安装了对吧
# /root/ansible/mycollection/ansible_collections

ansible.netcommon 6.1.1  
ansible.utils     4.1.0  

再次执行这个playbook

[root@localhost ansible]# ansible-playbook test6.yml PLAY [test] *************************************************************************************************************************TASK [Gathering Facts] **************************************************************************************************************

# 这个时候他告诉我们没有netaddr这个python库
# 这里我们安装这个python库
# 也是我自己出错的点，你ansible使用的是哪个python版本
# 你就要使用哪个版本来安装netaddr这个python库才行

解决问题

先查看ansible版本

[root@localhost ansible]# ansible --version
ansible [core 2.14.2]config file = /root/ansible/ansible.cfgconfigured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']ansible python module location = /usr/lib/python3.11/site-packages/ansibleansible collection location = /root/ansible/mycollection:/root/ansible/{{ ANSIBLE_HOME ~ "/collections:/usr/share/ansible/collections" }}executable location = /usr/bin/ansiblepython version = 3.11.2 (main, Feb 16 2023, 00:00:00) [GCC 11.3.1 20221121 (Red Hat 11.3.1-4)] (/usr/bin/python3.11)jinja version = 3.1.2libyaml = True
# 用的python3.11对吧
# 使用python3.11安装netaddr

安装netaddr这个python库

# 安装pip3.11
[root@localhost ansible]# yum install -y python3.11-pip.noarch 
# 创建python虚拟环境
python3.11 -m venv python_env
source python_env/bin/activate
(python_env) [root@localhost ansible]# pip3.11 install netaddr
