You could try using --skip-broken to work around the problem

缘由：epel源与python版本冲突缘由，从上图能够看出，有些包是须要依赖python2.6的版本，此主机的python版本是2.7.5。json
解决办法：缓存
一、先卸载 epel-release源，ui
#yum install epel-release -yspa
二、到 /etc/yum.repos.d 目录下，将epel.repo源备份，blog
#mv epel.repo epel.repo.bakip
三、清理yum源缓存和新建缓存，rem
# yum clean allstring
# yum makecache
四、再执行安装命令：#yum install ansible -y
五、#ansible --version
检测Ansible安装是否成功，输出下图所示，则表示成功。
