[Ansible][Fedora 24] DNF模块需要python2-dnf，但它已经安装好了

Question

我有一个内部网络上的计算机没有连接到互联网，并复制了相关的rpm包到我的本地dnf存储库。我试图让ansible的DNF模块在另一台计算机上安装一个程序，但是它会弹出一条错误消息，说明python2-dnf没有安装。但是当我试图安装这个程序时，它已经安装好了。有人知道出什么问题了吗？

我把错误代码放在下面。

背景：

Ansible Control machine: Fedora 24 4.5.5-300.fc24.x86_64 GNU/LINUX
Ansible Client machine: Fedora 24 4.5.5-300.fc24.x86_64 GNU/LINUX 
yum/dnf local repository: Centos 7 3.10.0-327.28.3.el7.x86_64 GNU/LINUX

root@localhost ansible# ansible all -m dnf -a "name=vim state=present“

, "msg": "python2-dnf is not installed, but it is required for the Ansible dnf module." 
} 

root@localhost ansible# yum安装python2-dnf

Yum command has been deprecated, redirecting to '/usr/bin/dnf install python2-dnf'. 
See 'man dnf' and 'man yum2dnf' for more information. 
To transfer transaction metadata from yum to DNF, run: 
'dnf install python-dnf-plugins-extras-migrate && dnf-2 migrate'

正如@GUIDO所指出的，目标主机上需要python2-dnf。

不可测模块文档声明：

需求(在执行模块的主机上) python 2.6 python

在执行模块的主机上，意味着在Ansible上下文中播放的目标主机，而不是控制主机。
