Abandoned: 15 packages were abandoned.

you are missing the catkin_pkg in your python. Try to install it via "(sudo) pip install catkin_pkg" or "pip3 install catkin_pkg".

Or google the error message, Import error, no module named "catkin_pkg". I believe you can find the answer.

I have run all the commands you have told me.
Also I tried to run: sudo apt-get install python-catkin-pkg
In all cases the catkin_pkg is installed in the system.
Also googling the message didn't gave me any solutions.
Do you have any more propositions?
Thank you very much.

Hmmm, it looks like a catkin/python/ROS problem.

Did you build other ROS projects on your machine before?

Hi @sotomotocross, do you get a new error after installing catkin_pkg? Or does from catkin_pkg.package import parse_package still cause an error?

[yun-long]

closing the issue. it seems like a ROS installation problem. feel free to reopen it if the issue still exists.

[sotomotocross]

Excuse me for the lack of feedback. I was with another project.
The error still exists. I tried to install the flightmare on a new Ubuntu 18.04.05 LTS system and i have the problem of the two attached screenshots.


I have installed the below:

1. sudo apt install python-catkin-pkg python-catkin-tools
2. pip install catkin-tools
3. pip install catkin-tools-python
4. sudo -H pip install -U catkin_pkg

Still the error doesn't stop appearing.
I have run catkin build before on this system and everything run ok. Especially earlier today i built https://github.com/uzh-rpg/rpg_esim that uses similar steps.

I don't know what else to do and i really need any help available.
Thank you in advance for the cooperation, time and help.
Looking forward to here from someone.

Initialize your build for python 2.7. It seems your catkin tools point to python 3.7.
Do this in your workspace directory (~/catkin_ws)
catkin config --init --mkdirs --extend /opt/ros/$ROS_DISTRO --merge-devel --cmake-args -DCMAKE_BUILD_TYPE=Release -DPYTHON_VERSION=2.7

In case it helps, I was having the same issue (in Ubuntu 18.04 + ROS Melodic), and

sudo apt install python3-pip
pip3 install catkin_pkg

(as suggested above) solved the problem
