Do you stuck in catkin_make problem?

summary : delete catkin_ws and reinstall. That is the best answer.

 

I ate up a HUGE amount of snacks because of stress from catkin_make.

By the ROS tutorials, I'm on step of making catkin workspace.

Until I made folder named catkin_ws, it worked.

However when I tried to build? whatever input catkin_make on my shell,

there's an error

-----------------------------------------------------------------------------------------------------

I kept trying to fix this.

Move $pythonpath, delete devel folder, open all files on error line,,,,

BUT IT ALL NEVER WORK

 

so, i just remove all installed catkin stuff, and reinstall!

 

sudo apt-get remove --auto-remove catkin

sudo apt-get purge catkin

rm -r catkin_ws

 

sudo apt-get update

source /opt/ros/melodic/setup.bash

sudo apt-get install ros-melodic-catkin

sudo apt-get install cmake python-catkin-pkg python-empy python-nose python-setupto
ols libgtest-dev build-essential

 

and you can start on "mkdir -p ~/catkin_wr/src" from ros tutorial

HURRAY~~~~~

GOOD LUCK!
