A linha interessante é:

Failed building wheel for scandir

Como posso me livrar disso?

    

Answer 1

Tente isso:

$ sudo apt-get install python-dev

E tente novamente:

$ pip install ipython --user

Deve funcionar agora.

    

Answer 2

Eu acertei o mesmo erro Failed building wheel for scandir em um servidor Ubuntu 16.04. O problema raiz foi que o gcc não foi instalado e é usado para construir scandir .

Depois de instalar o gcc, o problema desapareceu:

sudo apt-get install gcc

Eu acho que o problema do OP está relacionado à falta de arquivos de cabeçalho (não faltando o gcc), mas eu pensei em mencionar isso aqui, já que os usuários que estão faltando no gcc provavelmente também encontrarão esta página.
