Amazon ec2 Ansible error从主机接收到退出状态

我编写了一个看似简单的ansible任务来连接ec2实例并配置时区。主要任务如下

---
- name: Set Time Zone variables
  copy: content='Etc/UTC' dest=/etc/timezone owner=root group=root mode=0644 backup=yes

用于运行任务的命令是

ansible-playbook nectar.yml  --extra-vars "ansible_python_interpreter=/usr/local/bin/python env=DEVELOPMENT" -vvvv

我的ansible.cfg看起来像

[defaults]
inventory = hosts

[ssh_connection]
ssh_args = -o ControlMaster=auto -o ControlPersist=60s

但我一直收到错误信息

你知道为什么ansible在重用主连接时总是出现这个错误吗？

如果我必须在ubuntu AMI上运行一些东西，我会在playbook上做类似的事情

---
- hosts: all
  remote_user: someuser
  gather_facts: False
  pre_tasks:
    - name: Install python for Ansible
      raw: test -f /usr/bin/python || (apt -y update && apt install -y python-minimal)
      become: true
```

- setup: # aka gather_facts

---

尝试在目标计算机上安装python。 我有同样的错误：

dworker-01 | FAILED! => {
    "changed": false,
    "module_stderr": "Shared connection to dworker-01 closed.\r\n",
    "module_stdout": "/bin/sh: 1: /usr/local/bin/python: not found\r\n",
    "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error",
    "rc": 127
}

目标机器：

apt-get-update&&apt-get-install-python

---

之后一切正常。

您试图在远程主机上执行

/usr/local/bin/python

，错误消息告诉您，它不在那里。
