This is the first part of my code:

#!/usr/bin/env python

import os
import sys
import signal
import rospy
import time

Even then I got the error saying that:

line 1:#!/usr/bin/env: no such file or directory
line 3: import command not found

how ever it is working normally when I run with Python Before running it I even did this

source ~/catkin_ws/devel/setup.bash
