Test problem

[Paul Jurczak]

I'm following instructions to test RobotOS package on Ubuntu 18.04 with Python 2.7 and I'm getting

PyError (PyImport_ImportModule

The Python package fake_msgs.msg could not be found by pyimport. Usually this means
that you did not install fake_msgs.msg in the Python version being used by PyCall.

I don't know how to install the Python package containing the fake_msgs.msg module. What is the name of this package?

I also noticed that one of the processes required for the test, fails:

paul@paul-desktop:~/.julia/packages/RobotOS/OnyF4/test$ ./echonode.py

Hi @pauljurczak,

In the first comment, the package is actually testing that the system errors when you ask to create a message type that doesn't exist (fake_msgs.msg.FakeMsg), so that is working properly.

For the second comment, I'm not sure what that error is, but since it happens when running a normal python ROS node it is probably an issue with your system in particular and not something to do with Julia or this package.

Thanks!
