【已处理/安装问题】ansible-playbook -i inventory/hosts setup.yml ERROR! no action detected in task

ansible-playbook -i inventory/hosts setup.yml
ERROR! no action detected in task

The error appears to have been in '/opt/rainbond/rainbond-ansible/roles/prepare/tasks/main.yml': line 12, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

• import_tasks: offline.yml
  ^ here

已经解决；
原因是ansible版本过低，通过ansible -version命令查看版本为2.0，目前为2.8版本，升级版本后可以使用。
版本升级步骤：
1.Add the following line to /etc/apt/sources.list:
deb http://ppa.launchpad.net/ansible/ansible/ubuntu trusty main
2.Then run these commands:
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 93C4A3FD7BB9C367
$ sudo apt update
$ sudo apt install ansible
