使用 ipaddr 过滤器过滤 mac 地址的问题

Question

我会使用 ipaddr 过滤器检查输入的 mac_address 语法，这需要 netaddr python 包才能使用它。 netaddr 已安装在我的控制器中

Requirement already satisfied: netaddr in /usr/lib/python3.6/site-packages (0.7.19)

但是当我运行剧本时，我得到的是

---
  - name: test MAC address manipulation
    hosts: all
    strategy: free
    gather_facts: no
    connection: local
    no_log: false

    # vars_prompt:
      # - name: "macaddress"
        # prompt: "mac address?"
        # private: no

    vars:
      macaddress: "1a-2b-3c-4d-5e-6f"

    tasks:
      - name: display all the formats
        ignore_errors: true
        debug:
           msg:
             - Original = {{ macaddress  }}
             - ""
             - "{ macaddress | ansible.utils.hwaddr('bool') }        = {{ macaddress | ansible.utils.hwaddr('bool') }}"

剧本执行

这是ansible和python版本

ansible [core 2.12.5]
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.8/site-packages/ansible
  ansible collection location = /home/x/.ansible/collections:/usr/share/ansible/collections
  executable location = /usr/bin/ansible
  python version = 3.8.12 (default, Sep 21 2021, 00:10:52) [GCC 8.5.0 20210514 (Red Hat 8.5.0-3)]
  jinja version = 2.10.3
  libyaml = True

您已在 python3.6 库中的控制器上安装了 netaddr，但您的 Ansible 使用的是 python3.8。

     python3.8 -m pip install netaddr

或者使用 virtualenv。
