"catkin_make" must be invoked in the root of workspace

edit

Hi, I've got this problem, I saw other people with it, but answer on their topic didn't help me So i exactly have The specified base path "/home/eisti/catkin_ws/src/turtlesim_cleaner" contains a package but "catkin_make" must be invoked in the root of workspace When I try

~/catkin_ws/src/turtlesim_cleaner$ catkin_make

I'm just trying to do this tutorial

So the last things to do in this tutorials doesn't work " rosrun turtlesim_cleaner move.py" I think it's because of that, but I don't know how to fix this, I just follow the turorials

this is my workespace

catkin_ws/
     /build
     /devel
    /frames.gv
    /frames.pdf
   /install
   /src (in this one)
        /beginner_tutorials
        /CMakeLists.txt
        /learning_tf
        /turtlesim_cleaner

Edit:

Thank you,

In fact I had an other problem and I thougth it was from this catkin_make, but it wasn't I had a rospack error, like this, and solve it with this topic

But I still do not understant this line in the tutorial

$ cd ~/catkin_ws/src/turtlesim_cleaner 
$ mkdir src 
$ catkin_make

because like this catkin_make can't work
