I found this being mentioned in an issue on ansible from 2015: https://github.com/ansible/ansible-modules-core/issues/688

What ansible version are you using?

Try updating your ansible version to have a recent version (I have 2.9.7 now, the README says 2.5 is the minimum, but it may need to be updated).

Then you should try to run the playbook again. If that fixes it, let me know and I'll update the min version advised.

If it doesn't you can try installing python virtualenv manually on the system.

For some reason ansible is not installing the python virtual environment package correctly, which is a requirement, I've seen this error on other occasions, I thought it was fixed.

I hope this helps.

Hi Federico,

It works after I installed the python virtualenv manually on the system.  The ansible version is 2.9.13.

I had the same issue on Ubuntu and the solution was to add python-virtualenv to the pkg list

    - name: install webserver components

      apt:

        pkg:

        - apache2

        - libapache2-mod-wsgi-py3

        - python3-pip

        - python-virtualenv

        state: present

        update_cache: yes
