I'm tying to install a micro-ROS development on my Macbook (Mohave) and have run into issues after the following steps:

# Create a workspace and download the micro-ROS tools
mkdir microros_ws
cd microros_ws
git clone -b $ROS_DISTRO https://github.com/micro-ROS/micro_ros_setup.git src/micro_ros_setup

# Update dependencies using rosdep
sudo apt update && rosdep update
rosdep install --from-path src --ignore-src -y

I end up with the error:

ERROR: the following packages/stacks could not have their rosdep keys resolved
to system dependencies:
micro_ros_setup: No definition of [python3-vcstool] for OS [osx]

My python version is Python 3.9.0. ROS2 version is Foxy

Can anyone help with this issue?

Hi mjwhite, I got the same problem when I install MicroRos on my macbook_pro. Do you have the issue fixed? Thank you.

Hi Elk_liu, No sorry, I didn't get this working. I ended up getting a linux desktop since I've had only limited success with getting my Macbook setup as a ROS development environment.

Looking at ros/rosdistro/rosdep/python.yaml it appears there is indeed no key for osx:

python3-vcstool:
  alpine: [vcstool]
  debian:
    pip:
      packages: [vcstool]
  fedora: [python3-vcstool]
  gentoo:
    pip:
      packages: [vcstool]
  macports:
    pip:
      packages: [vcstool]
  ubuntu: [python3-vcstool]

That would be the cause of the error.

If python3-vcstool is a valid package name on OSX (for whichever package manager is used), you could contribute an update to that rule. That would resolve the error.

So I've overcome the problem by updating that rosdep rule for OSX. I also had to update the rules for about six other packages for OSX. One of those packages was "wget" which I would have thought would have been added already since ROS2 is supported on OSX. I'm having all sorts of other problems installing micro-ROS on my Macbook, which leads me to believe that OSX may not be a good option for ROS2 development. Would it be advised to get a Linux computer?

have you submitted those changes as pull requests? I don't see them over at github.com/ros/rosdistro?

I just added it. I hadn't finished installing micro-ROS and I wanted to make sure I had all of the required packages. There are 11 packages in the pull request.

@mjwhite can you link that pull request when it's open? I just looked and didn't see it, but maybe I missed it.

I removed the request since I couldn't get nosetests installed on the Mac either. I've setup a Linux machine for now and everything is working fine there. So I'll try the Mac at a later date. Thanks for your help.
