AWX & virtual environment setup to support Python3

I’m rather confused about how to setup and configure virtual environments in AWX. In order to support a dynamic inventory script which required Python3.6 (on AWX 3.0.1) I created a virtual environment as below.

yum install -y make gcc python36-devel
virtualenv /var/lib/awx/venv/cnd
source /var/lib/awx/venv/cnd/bin/activate
&& umask 0022
&& python3 -m pip install python-memcached psutil textfsm
&& python3 -m pip install -r /tmp/requirements36.txt

= requirements36.txt =

=2.1.1
=0.2.4
=2.2.0
urllib3>=1.24
=4.2.5

When I run the job template I get the error “ERROR! Unexpected Exception, this is probably a bug: psutil is missing; /var/lib/awx/venv/cnd/bin/pip install psutil”.

The job template is configured to use the created venv (cnd) as is the organization that contains it as well as the associated projects (for inventory sources and playbook) are configured in.

The cnd venv seems to contain psutil

Any suggestions?

I don’t know what you’re running into but I know the the syntax for creating virtualenvs is different in python3 – python3 uses venv whereas you’re using virtualenv, a python2 style venv. I’m using more or less the same code in the custom virtualenv docs and using virtualenvs successfully. Give that a shot and see if it works
