Issue

When I try to run roslaunch flock_base teleop.launch

Source of the issue

I get a message ImportError: No module named av and when I want to install this module with pip install av I get another error:

    from shlex import quote
ImportError: cannot import name quote

Finally, when I try to install this module with pip install shlex I obtain the following:

ERROR: Could not find a version that satisfies the requirement shlex (from versions: none)
ERROR: No matching distribution found for shlex

Question

How can I install the necessary packages to get it to work? Should I try to remove all the components that use the av module? Is this issue known to someone that used this package?

System informations

I tested it on Ubuntu 16.04 with ROS Kinetic and on Ubuntu 18.04 with ROS Melodic and in both cases I have the same errors.
