ansible在easy_install中提示输入ssh密码

团队， 我需要使用我的macbook抱怨dnspython需要的dig模块。所以我用easy_install安装它，但我得到提示输入密码。如何使其无密码

      - easy_install:
          name: dnspython
          state: present
        become: yes

      - name: Validate DNS record lookup for {{ kubeapi_server }}
        debug: msg="{{ lookup('dig', '{{ kubeapi_server }}' )}}"
        vars:
          variable: "{{ lookup('dig', '{{ kubeapi_server }}' )}}"
        failed_when: not variable

输出1：带-k选项

ansible-playbook -i inventory.txt playbook.yaml -k -K
SSH password: 
BECOME password[defaults to SSH password]: 

输出1：不带-k-k选项

ansible-playbook -i inventory.txt playbook.yaml

可能的原因可能是： 1.您没有在主机清单中指定密码。 2.用户的sudo权限应该是主机的/etc/sudoers中的NOPASSWD:ALL
