python - 我收到消息 : "The pexpect python module is required" when running pexpect module on ansible

Question

我对ansible非常陌生，我正在尝试运行一个剧本来更改主机的root密码，所以我使用pexpect模块的expect命令。我成功地在主机和运行 playbook 的本地服务器上安装了带有 python 2.7 的 pexpect v4.7。然而，当剧本运行时，它失败并出现错误:“需要 pexpect python 模块”

根据要求，pexpect和python版本正确

Files installed on hosts for pexpect and python: 
/usr/lib/python2.7/site-packages/pexpect
/usr/lib/python2.7/site-packages/pexpect-4.7.0-py2.7.egg-info
/usr/pexpect-4.7.0
/usr/pexpect-4.7.0/doc/api/pexpect.rst
/usr/pexpect-4.7.0/pexpect.egg-info
/usr/pexpect-4.7.0/tests/pexpectTest.py
/usr/pexpect-4.7.0/pexpect
/usr/pexpect-4.7.0/build/lib/pexpect

剧本如下:

---
- hosts: all
  become: true

  tasks:
    - name: change password for root user
      expect: 
        command: passwd root
        responses: 
           (?i)password: "password"

我做错了什么吗？请帮忙!

Answer 1

我通过从所有主机中删除 pexpect 然后相应地安装 epel-release、pip 和 pexpect 包来解决这个问题。
