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

Question

当我将主机的 ansible_python_interpreter 的值设置为 /usr/bin/python3 时，ansible-playbook 似乎仍在使用指向 python2.7 的 /usr/bin/python 我从输出显示的 -vvv 得到这个

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

我在我的 yml 文件中进行了调试，用于输出变量并返回：

"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)]

我已将库存文件中的位置转移为第一个变量，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，脚本运行正确

库存文件

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

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）"

变量必须与主机在同一行。

[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

与主机

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

剧情

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

给予

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

，但下面有主机

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

同样的播放失败

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