yum makecache: error: argument timer: invalid choice: ‘fast‘ (choose from ‘timer‘)

yum makecache: error: argument timer: invalid choice: ‘fast’ (choose from ‘timer’)

在使用yum makecache fast报错yum makecache: error: argument timer: invalid choice: ‘fast’ (choose from ‘timer’)，是因为CentOS 8没有fast这个命令 去掉就可以了
