ansible主机连通性测试报错

报错提示

[root@yx01 site-packages]# ansible all -m ping
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit
localhost does not match 'all'
/usr/lib/python2.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.25.3) or chardet (2.2.1) doesn't match a supported version!
  RequestsDependencyWarning)

显示urllib3 (1.25.3) or chardet (2.2.1)版本不匹配
使用pip命令删除库

pip uninstall urllib3
pip uninstall chardet

但是还是报相同的错误
在依赖库的目录/usr/lib/python2.7/site-packages/下发现还是有其它版本的urllib3和chardet

手动删除后再使用ansible all -m ping可以成功
