Ansible is using wrong version of Python

I have been dealing with this issue for a couple of days now. I am running ansible on a raspberry pi. I have made Python3.7 the default version of Python. Apparently Ansible wants to use Python 2.7. I have added Version 3.7 in the vars in the playbook but this does not change the module location. It still looks for the modules in Python 2.7.

I am not sure how to tell Ansible to use 3.7 for all the modules and the interpreter.

pi@pi:~ $ python --version
Python 3.7.2
pi@pi:~ $ ansible-playbook vm.yaml -vv
ansible-playbook 2.9.6
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/pi/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible-playbook
  python version = 2.7.16 (default, Oct 10 2019, 22:02:15) [GCC 8.3.0]
Using /etc/ansible/ansible.cfg as config file
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'

Solution

You probably need to change this.

ansible-playbook 2.9.6
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/home/pi/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/dist-packages/ansible
  executable location = /usr/bin/ansible-playbook
  python version = 2.7.16 (default, Oct 10 2019, 22:02:15) [GCC 8.3.0]

python version is defined as 2.7.16, which you need to change.
