Hello there!

I got this issue while running a basic playbook (ping) in AWX platform.

Below, you can notice that I installed the same python depandancies in both awx docker containers ( Awx\_task and Awx\_web).

- Awx\_task

- virtualenv : test\_virtualenv

- ansible 2.4.3

- psutil 5.4.6

- python-memcached 1.59- Awx\_web

- virtualenv: test\_virtualenv

- ansible 2.4.3

- psutil 5.4.6

- python-memcached 1.59

Here the logs I captured through AWX web browser:

ansible-playbook 2.4.3.0

config file = /etc/ansible/ansible.cfg

configured module search path = [u’/var/lib/awx/.ansible/plugins/modules’, u’/usr/share/ansible/plugins/modules’]

ansible python module location = /var/lib/awx/venv/test\_venv/lib/python2.7/site-packages/ansible

executable location = /var/lib/awx/venv/test\_venv/bin/ansible-playbook

python version = 2.7.5 (default, Feb 20 2018, 09:19:12) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)]

Using /etc/ansible/ansible.cfg as config file

SSH password:

Parsed /tmp/awx\_189\_yncRCn/tmpmeMQez inventory source with script plugin

ERROR! Unexpected Exception, this is probably a bug: No module named psutil

the full traceback was:

It looks like you’re using a custom virtualenv; awx doesn’t install anything in custom virtualenvs by default.

/var/lib/awx/venv/test\_venv

You’ll need to install psutil and python-memcached at least. You may consider just installing this base list of dependencies: [https://github.com/ansible/awx/blob/devel/requirements/requirements\_ansible.in](https://github.com/ansible/awx/blob/devel/requirements/requirements_ansible.in)

Yes it works.

I have just installed psutil version 5.4.3 in both containers (awx\_task and awx\_web).

Thanks Ryan.
