Cannot find neither ~/.ansible.cfg or etc/ansible - ansible

Question

I installed ansible using pip
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python get-pip.py
sudo pip install ansible
But I cannot find either ~/.ansible.cfg or etc/ansible in macOS.
$ansible --version

ansible 2.10.0.dev0
config file = None
configured module search path = [u'/Users/nethminiromina/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
ansible python module location = /Users/nethminiromina/Library/Python/2.7/lib/python/site-packages/ansible
executable location = /usr/local/bin/ansible

How can I find or setup inventory file?

Answer 1

Q: "Cannot find etc/ansible"
A: pip show -f ansible should show the installed files. If the configuration file is missing create one. See Configuring Ansible.

You can use ansible-config to show the config file location
% ansible-config --version
ansible-config [core 2.13.1]
config file = None
configured module search path = ['/Users/myusername/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/ansible
ansible collection location = /Users/myusername/.ansible/collections:/usr/share/ansible/collections
executable location = /Library/Frameworks/Python.framework/Versions/3.9/bin/ansible-config
python version = 3.9.7 (v3.9.7:1016ef3790, Aug 30 2021, 16:39:15) [Clang 6.0 (clang-600.0.57)]
jinja version = 3.1.2
libyaml = True
In this case I had no configuration file (config file = None) so I generated an empty one (option --disabled means all entries are commented out) in the current directory with
% ansible-config init --disabled > ansible.cfg
Now ansible-config can find a configuration file in the current directory /localDir
% ansible-config --version
ansible-config [core 2.13.1]
config file = /localDir/ansible.cfg
[ . . . ]
Note: consider security issues Avoiding security risks with ansible.cfg in the current directory.
Here's the priority list of places where Ansible will search for a config file (see configuration file):
ANSIBLE_CONFIG (environment variable if set)
ansible.cfg (in the current directory)
~/.ansible.cfg (in the home directory)
/etc/ansible/ansible.cfg
