Ich habe also versucht, die WSL-Ubuntu-App zu verwenden, damit ich dieses ROS nutzen kann, aber ich verstehe nicht genau, was ich falsch gemacht habe. Ich habe versucht, diese Befehlszeile zu verwenden:
$ catkin_make
aber dann würde es heißen, dass ich eine Art Importfehler habe und ich um Himmels Willen nicht die geringste Ahnung habe, wie ich ihn lösen soll:

Make sure that you have installed "catkin_pkg", it is up to date and on the PYTHONPATH.

und geben Sie diese Befehlszeile ein:
$ cd ~/catkin_ws/src
würde dieses Ergebnis liefern:
bash: cd: /root/catkin_ws/src: No such file or directory
Allerdings konnte ich dieses sogenannte Verzeichnis „Verzeichnis“ in keinem meiner Ordner auf meinem Computer finden, was mir einfach ein Rätsel ist.
Muss ich noch etwas anderes installieren? Oder soll ich einfach einen neuen Ordner mit dem Namen „src“ in dem Verzeichnis erstellen, von dem in der Eingabeaufforderung immer wieder die Rede ist?
