Ubuntu – rosrun can't find executables even though {workspace_directory}/devel/setup.bash was sourced correctly

I have sourced the /opt/ros/noetic/setup.bash and my workspace correctly. But still I can’t find my nodes inside the package throgh autocompletion (pressing TAB key). If I type in the name manually, it returns a error saying "[rosrun] Couldn’t find executable named raspicam_node below"

I looked in CMakeFiles and everything was formatted correctly.

    Make sure you have enabled read-write permission in the workspace directory.

    $ chmod u+x -R {workspace_directory}

    Running this before I wanted to run a node fixed my issue.

    You need to make sure that you have given execution as well as read/write permissions in the cmake directory or where the nodes are located.

    $ sudo chmod 777 -R {directory}

    Try and run this before you execute the files.
    Or configure the setup bash again.
