在通过kubespray 安装k8s集群时，运行命令：
time kubespray deploy --verbose -u root -k .ssh/id_rsa -n flannel出现错误：
The error appears to have been in '/xx/kubernetes-project/kubespray/roles/vault/handlers/main.yml': line 44, column 3, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: unseal vault
^ here环境：cento7
问题解决：
1.卸载 ansible，然后重装 ：
pip uninstall ansible
pip install ansible2.卸载hashivault ，然后重装：
pip uninstall ansible-modules-hashivault
pip install ansible-modules-hashivault在使用时没用 sudo 。
3.重新运行kubespray 命令来装即可。
