catkin_ws$ source ~/catkin_ws/devel/setup.bash

but it needs to run this command every close and open again, how to solve this issue??

second part:

I read from the previous questions and answers to other people, solving this problem by 

gedit ~/.bashrc

then

export ROS_PACKAGE_PATH=/home/redhwan/catkin_ws/:$ROS_PACKAGE_PATH

finally

source ~/catkin_ws/devel/setup.bash    & source ~/.bashrc

not solve my issue

Having to source the workspace is not a bug, it's intended behaviour. Say you have multiple workspaces, you only want to source the one that's relevant to you right now. You could "solve it by adding the command to bashrc but I do not recommend it.

With regards to the import error, you'll have to post the code you're tying to run.
