py3-ready 0.1.0

Install

This package works on Ubuntu and Debian, and it needs some packages installed on the system.

Install these if the default python is Python 2 (Ubuntu Bionic, Debian Stretch, etc).

$ sudo apt-get install python-apt
$ sudo apt-get install python-rosdep-modules
$ sudo apt-get install python-catkin-pkg-modules

Install these if the default python is Python 3 (Ubuntu focal, Debian Buster, etc).

$ sudo apt-get install python3-apt
$ sudo apt-get install python3-rosdep-modules
$ sudo apt-get install python3-catkin-pkg-modules

Then install from PyPI.org.

$ pip install py3-ready

If you would like to install from source then create a virtual environment with access to system packages.

$ cd py3-ready/
# Set up Python 2 virtual environment
$ virtualenv --system-site-packages ssenv2
$ . ssenv2/bin/activate
$ python setup.py develop
$ deactivate
# Set up Python 3 virtual environment
$ python3 venv --system-site-packages ssenv3
$ . ssenv3/bin/activate
$ python setup.py develop

Usage

All commands exit with code 1 if the package does depend on python 2, and 0 if does not. If any unrecoverable error occurs then the exit code is 2.
