lemp_ubuntu1804 playbook ends with PyMySQL failure

[eran101]

This is how the playbook ends:

TASK [Sets the root password] *****************************************************************************************************
[WARNING]: Module did not set no_log for update_password
fatal: [localhost]: FAILED! => {"changed": false, "msg": "The PyMySQL (Python 2.7 and Python 3.X) or MySQL-python (Python 2.X) module is required."}

RUNNING HANDLER [Reload Nginx] ****************************************************************************************************

PLAY RECAP ************************************************************************************************************************
localhost : ok=6 changed=5 unreachable=0 failed=1 skipped=0 rescued=0 ignored=0

The PyMySQL was already installed when the playbook finished:

Reading package lists... Done

python3-pymysql is already the newest version (0.8.0-1).

@eran101 I was getting this same error as well. In vars/default.yml file I added ansible_python_interpreter: "/usr/bin/python3"

There was also a prior warning in the terminal "[DEPRECATION WARNING]: Distribution Ubuntu 18.04 on host default should use /usr/bin/python3, but is using /usr/bin/python for backward compatibility with
prior Ansible releases."

In the playbook Ansible is installing "python3-pymysql" and using the python 2.7 interpreter to execute the package which is a python 3 package.

Telling Ansible to use the Python 3 interpreter fixed the error.
