I exactly followed the instructions from http://wiki.ros.org/melodic/Installation/Ubuntu.
Then I created a workspace by
cd
mkdior -p catkin_ws/src
cd catkin_ws/src
catkin_init_workspace
cd ..
catkin_make
The I got
Traceback (most recent call last):
File "/opt/ros/melodic/bin/catkin_make", line 13, in
from catkin.terminal_color import disable_ANSI_colors, fmt
File "/opt/ros/melodic/lib/python2.7/dist-packages/catkin/terminal_color.py", line 2, in
from catkin_pkg.terminal_color import * # noqa
ImportError: No module named terminal_color
I googled and tried everything I could(except for reinstalling my OS). But the problem is still there.
For example, to give more info:
Run
sudo dpkg -L python-catkin-pkg
and got
