tasks/main.yml 文件是：

\n\n

---\n- name: AddUser in the server\n  user: \n   name: ansible\n   password: $6$sHQAZJ32E$ujHauabN7ZTbOQ/zhT5899EIaFErOecXYvTEyhekexy4dydsAXTGdUpaB8M4fQf2UGpZgX/Zg2Uv6areeuv/r0\n   comment: Ansible Configuration Mgmt\n   shell: /bin/bash\n\n- name: Add SSH key to users home direcotory\n  authorized_key: \n   user: "{{ item.name }}"\n   key: "{{ item.file }}"\n   state: present\n  with_items: \n   - ssh_vars\n...\n

\n\n

vars/main.yml 文件是：

\n\n

---\nssh_vars:    \n - { name: "ansible" , file: \'ansible.pub\' }\n

当我运行这个角色时，我收到以下错误

\n\n

问题在于您使用的方式with_items：裸变量已经很长一段时间不受支持了。

像这样纠正你的循环：with_items: "{{ ssh_vars }}"
