La ligne intéressante est:

Failed building wheel for scandir

Comment pourrais-je me débarrasser de ça?

Essayez ça:

$ Sudo apt-get install python-dev

Et puis réessayez:

$ pip install ipython --user

Cela devrait fonctionner maintenant.

Je rencontre la même erreur Failed building wheel for scandir sur un serveur Ubuntu 16.04. Le problème fondamental était que gcc n'était pas installé et qu'il était utilisé pour construire scandir.

Après avoir installé gcc, le problème a disparu:

Sudo apt-get install gcc

Je pense que le problème de l'OP est lié aux fichiers d'en-tête manquants (pas à gcc), mais je pensais le mentionner ici car les utilisateurs manquants gcc trouveront probablement aussi cette page.
