travis build is failing #9

Closed felixduvallet closed 7 years ago

As of the latest travis image update, this script is no longer working. (I'm looking into it, but please post any ideas you might have)

The Travis build fails due to a python import error:

ImportError: "from catkin_pkg.package import parse_package" failed
No module named catkin_pkg.package

The root cause is that Travis upgraded their trusty images (specifically from connie-trusty to sugilite-trusty, see here), which put the python binary into /opt/python/2.7.13 (and the python search path was updated accordingly).

However, since all ROS dependencies are installed by apt-get into /usr/lib/python2.7 (which is not in the python system path), any python-related ROS calls failed (including building).

The fix (see #10 ) is to manually add /usr/lib/python2.7 into the PYTHONPATH environment variable to ensure that python is able to find all required packages once they are installed via apt-get.

Note that this isn't exactly the Travis-recommended way of installing python packages (they recommend using pip instead of apt-get), but this method is compatible with the ROS dependency management.
