ModuleNotFoundError: No module named rospkg

Hi all,

I know this questions has been asked many times but when go to the catkin workspace and compile astra_camera this error appeared:

   from roslib.launcher import load_manifest
  File "/opt/ros/melodic/lib/python2.7/dist-packages/roslib/launcher.py", line 42, in <module>
    import rospkg
ModuleNotFoundError: No module named 'rospkg'

I'm currently using ros melodic with raspbian buster on a Pi4 4gb i have tried to change the python path and reinstall the rospkg but still this error.

Please help me :(

i had tried this solution but it still gave back me the same error reinstall

i have also tried (export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.7/dist-packages) but this gave me error of python not working

i have also tried this method 

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 100 
sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 150

but still the same error

majority that faced this issue has anaconda installed that caused the pythonpath to change.

these are my pythonpaths,

/home/pi/catkin_ws/devel/lib/python2.7/dist-packages
/opt/ros/melodic/lib/python2.7/dist-packages
/opt/ros/melodic/lib/python2.7/dist-packages/python_qt_binding-0.3.5-py2.7.egg
/usr/lib/python37.zip
/usr/lib/python3.7
/usr/lib/python3.7/lib-dynload
/home/pi/.local/lib/python3.7/site-packages
/usr/local/lib/python
