“msg”: “Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this. Please add this host’s fingerprint to your known_hosts file to manage this host.”

ssh第一次连接的时候一般会提示输入yes 进行确认为将key字符串加入到 ~/.ssh/known_hosts 文件中。
而本机的~/.ssh/known_hosts文件中并有fingerprint key串
解决方法：在ansible.cfg文件中使用host_key_checking = False
