这种错误可能是目标主机上安装了两个版本的python，python2 和python3

这里有两个可用的办法：

1. -e添加变量#

ansible_python_interpreter这个变量设置了使用哪个版本的python。

}
[root@CentOS7.9]# ansible -i ans del -m shell -a "df -h"  -e ansible_python_interpreter=/usr/bin/python3

但是缺点也很明显，每次都要加上这个特别麻烦，来看第二个方法，一步到位。

2. 把变量添加到hosts#

找到hosts列表编辑

vim ans 在ip地址后加上 ansible_python_interpreter=/usr/bin/python3 保存退出。

200.200.8.67 ansible_python_interpreter=/usr/bin/python3

这次可以了

[root@CentOS7.9]# ansible -i ans del -m shell -a "df -h"
