Quando tento executar o comando: ansible wordpress -u vagrant -i hosts -m shell -a 'echo Hello, World' aparecem essas mensagens de erro. Estou tentando utilizar a máquina do ansible que foi feita no curso do Vagrant.

[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'
