RHCE 애러 모음 : [WARNING] /etc/ansible/hosts

Incorrect formatting of the host’s file may also result in the error below:

[WARNING]:  * Failed to parse /etc/ansible/hosts with yaml plugin: YAML
inventory has invalid structure, it should be a dictionary, got: <class
'ansible.parsing.yaml.objects.AnsibleUnicode'>
[WARNING]:  * Failed to parse /etc/ansible/hosts with ini plugin:
/etc/ansible/hosts:3: Expected key=value host variable assignment, got: ;
[WARNING]: Unable to parse /etc/ansible/hosts as an inventory source
[WARNING]: No inventory was parsed, only implicit localhost is available

위 에러 랑 똑같이 내보려고 이거저거 해보는데 동일한 애러를 낼수가 없다..

내가 이 에러 때문에 1시간을 허비 하고 결국 문제 다 못 풀고 떨어졌는데;;

같은 에러 어떻게 내는 거냐?
