Running into build issues again

I am getting into build issues repeatedly due to VM issues. Can you help me with steps to fix this?

Steps to reproduce:
cd /home/user/catkin_ws
rm -rf build/ devel/
source /home/user/.catkin_ws_python3/dnn_venv/bin/activate
source /home/user/.catkin_ws_python3/devel/setup.bash
catkin_make

got it fixed by rebuilding the workspace

Hi Shreyas I can see on your question that you were already rebuilding the workspace (since you were deleting the build and devel directories. Hence, your solution should have worked on the first place.

Can you explain a little bit which extra steps did you take to make it work. It may help other users.

@rtellez,
One clean way was to build another workspace and rebuild the current one from scratch.

I also did try few hacky way. My build was failing on gazebo plugin of other environment. I tried to find the files that were missing. replaced or added them to the repo. This fixed most of the errors. Later some part of my python script in my current build had to be updated correcting typos. This helped in resolving it.
