Makefile:61: recipe for target 'install' failed

edit

I am trying to setup ROS 1 with python 3 to create a wrapper for an application (yolo v4) . Unfortunately, ROS 1 and cv_bridge isn't that Python 3 friendly. So i am following this tutorial

  https://medium.com/@beta_b0t/how-to-setup-ros-with-python-3-44a69ca36674

to setup Python 3 with ROS. Everything runs fine until executing the last command, which is :

catkin_make_isolated --install --pkg rosunit -DCMAKE_BUILD_TYPE=Release --install-space /opt/ros/melodic

I get the following error message.
