“OSError:走出pty设备”与CentOS7上的易感塔

Question

我在CentOS 7上安装了ansible。我尝试运行一个剧本，但是每次我都会收到以下错误：

The full traceback is:
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/ansible/executor/task_executor.py", line 147, in run
    res = self._execute()
  File "/usr/lib/python2.7/site-packages/ansible/executor/task_executor.py", line 620, in _execute
    self._connection = self._get_connection(cvars, templar)
  File "/usr/lib/python2.7/site-packages/ansible/executor/task_executor.py", line 957, in _get_connection
    socket_path = start_connection(self._play_context, options, self._task._uuid)
  File "/usr/lib/python2.7/site-packages/ansible/executor/task_executor.py", line 1124, in start_connection
    master, slave = pty.openpty()
  File "/usr/lib64/python2.7/pty.py", line 29, in openpty
    master_fd, slave_name = _open_terminal()
  File "/usr/lib64/python2.7/pty.py", line 70, in _open_terminal
    raise os.error, 'out of pty devices'
OSError: out of pty devices
fatal: [SW1]: FAILED! => {
    "msg": "Unexpected failure during module execution.", 
    "stdout": ""
}

我还通过更改虚拟执行环境进行了测试，但它仍然无法工作。

    raise OSError('out of pty devices')
OSError: out of pty devices
fatal: [S1]: FAILED! => {
    "msg": "Unexpected failure during module execution.",
    "stdout": ""
}

我尝试手动启动剧本，而不使用Ansible Tower和"ansible- playbook“命令，它可以工作。

我遵照下列网站的指示：

• https://docs.ansible.com/ansible-tower/latest/html/upgrade-migration-guide/virtualenv.html#preparing-a-new-custom-virtualenv
• https://access.redhat.com/solutions/4371201

我还搜索了其他论坛，我没有找到其他人谁有同样的问题，我在Ansible塔。有人知道我怎么解决这个问题吗？
