Question

当我将主机的ansible_python_interpreter的值设置为/ usr / bin / python3时，ansible-playbook仍似乎使用/ usr / bin / python指向python2.7 我是从-vvv那里得到的，输出显示为

Using module file /usr/lib/python2.7/site-packages/ansible/modules/cloud/vmware/vmware_guest.py

我在yml文件中放入了一个调试程序，该调试程序将输出变量，并返回：

"ansible_python_interpreter": "/usr/bin/python3"

ansible --version
ansible 2.8.2
   config file = /ansible/automation/ansible.cfg
   configured module search path = ['/root/.ansible/plugins/modules', 
 '/usr/share/ansible/plugins/modules']
ansible python module location = /usr/local/lib/python3.6/site- 
packages/ansible
  executable location = /usr/local/bin/ansible
  python version = 3.6.8 (default, Apr 25 2019, 21:02:35) [GCC 4.8.5 
20150623 (Red Hat 4.8.5-36)]

我已将清单文件中的位置更改为第一个变量，并将其添加为组变量，但没有任何乐趣。

当我使用-e ansible_python_interpreter = / usr / bin / python3运行ansible-playbook命令时，脚本正确运行了

库存文件

[control] <REDACTED HOST NAME> ansible_connection=local ansible_python_interpreter=/usr/bin/python3

yml摘录

当进程运行时，出现此错误 “无法在Python / usr / bin / python2上导入所需的Python库（请求）”

变量必须与主机位于同一行。

[control]
REDACTED_HOST_NAME ansible_connection=local ansible_python_interpreter=/usr/bin/python3

使用group_vars更方便

[control]
REDACTED_HOST_NAME
[control:vars]
ansible_connection=local
ansible_python_interpreter=/usr/bin/python3

使用主机

localhost
[control]
REDACTED_HOST_NAME
[control:vars]
ansible_connection=local
ansible_python_interpreter=/usr/bin/python3

戏剧

- hosts: localhost
  gather_facts: no
  tasks:
    - debug:
        msg: "{{ hostvars['REDACTED_HOST_NAME'].ansible_python_interpreter }}"

给予

ok: [localhost] => {
    "msg": "/usr/bin/python3"
}

，但主机位于以下

localhost
[control]
REDACTED_HOST_NAME ansible_connection=local
ansible_python_interpreter=/usr/bin/python3

同一场比赛失败

'ansible.vars.hostvars.HostVarsVars object' has no attribute 'ansible_python_interpreter'

Ansible似乎没有从清单文件中加载ansible_python_interpreter = / usr / bin / python3变量
