Installation fails with pip3

See original GitHub issue

To reproduce this, rospkg and catkin-pkg also need to be installed to work with python3, e.g. using pip3:

$ pip3 install rospy-message-converter
Collecting rospy-message-converter
  Using cached
    Complete output from command python egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-build-1zv7ys8z/rospy-message-converter/", line 8, in <module>
        package_dir={'' : 'src'},
      File "/usr/local/lib/python3.5/dist-packages/catkin_pkg/", line 74, in generate_distutils_setup
        package = parse_package(package_xml_path)
      File "/usr/local/lib/python3.5/dist-packages/catkin_pkg/", line 513, in parse_package
        xml, filename = _get_package_xml(path)
      File "/usr/local/lib/python3.5/dist-packages/catkin_pkg/", line 489, in _get_package_xml
        raise IOError('Path "%s" is neither a directory containing a "%s" file nor a file' % (path, PACKAGE_MANIFEST_FILENAME))
    OSError: Path "." is neither a directory containing a "package.xml" file nor a file
Command "python egg_info" failed with error code 1 in /tmp/pip-build-1zv7ys8z/rospy-message-converter/

cjdscommented, Jun 7, 2020 has released a new version and now should work

mintarcommented, Aug 7, 2019

The pip library was made by @cjds (see #14 and #25), so any questions about that should go to him.

It’s not quite easy to set up Python3 with ROS at the moment, so I’m not sure what the proper fix for this would be. Pull requests welcome.
