$root@localhost \~$ # dnf --version
Traceback (most recent call last):

解决方法：

因为服务器环境为CentOS 7，没有完全预装在 CentOS 7 中，所以需要先全安装DNF。

yum install epel-release

yum install dnf

dnf --version

二、解决办法

1、先升级python:

#yum update python*

2、再安装以下软件：

bash 复制代码

yum -y install dnf-data dnf-plugins-core libdnf-devel libdnf python2-dnf-plugin-migrate dnf-automatic

3、测试

$root@localhost \~$ # dnf --version
