Python dependencies "wrapt" and "inflection" in 22.04 ROS 2

[matthias-mayr]

In ROS 1 we installed wrapt and inflection as pip packages with requirements.txt.
In ROS 2 Humble on 22.04 we used the system packages so far. This should be a more stable choice, however, there is currently no procedure to install them.

The easiest way is to have again an install script and/or some instructions.
The nice way would be to make a PR for rosdep and make a PR for a new rule and put them in the package.xml

Currently, does skiros2 support ROS 2 Humble? I look at the code is still using ros1 library ah, where to download support ROS 2 Humble project? Ask for advice

[matthias-mayr]

There is a ROS 2 branch that you can use and that works with humble. In the next weeks we are also working on a ROS 2 Jazzy version.

Seems like in the latest commit to the skiros2 master branch somebody added wrapt and inflection to the package.xml, but I don't think a rosdep rule has been made for them yet so installation (rosdep install --from-paths . --ignore-src --rosdistro=$ROS_DISTRO -y) is failing for me right now

In ROS 1 or ROS 2? In humble as well as Jazzy, I can resolve python3-wrapt and python3-inflection

Might be a ROS1 issue then? I'm on noetic, ubuntu 20.04

I just tested it in a fresh docker container derived from the ros:noetic image.

This container with a clone of this repo resolved python3-wrapt and python3-inflection when running a similar command to yours:
rosdep install --from-paths src --ignore-src --rosdistro=${ROS_DISTRO} -y although this was meant to be run from the workspace root.

This container reports running Ubuntu 20.04.6 LTS inside.

Sorry, I realized I simply forgot to do rosdep update.
