Como posso instalar o ipython com o pip3?

3

Eu fiz o seguinte sem problemas: 

brew install python3

pip3 install numpy

pip3 install scipy

Mas ao tentar: 

pip3 install ipython

Eu recebo: 

Exception:

Por que isso não funciona? Como posso contornar esses erros?

Você pode não ter permissão de gravação para o /usr/local/bin diretório. Para contornar isso, corra 

sudo pip3 install ipython

Você precisará digitar sua senha, supondo que você tenha privilégios de administrador no seu computador.

Você precisa configurar manualmente um comando ipython3?

@cbare Não, é feito automaticamente por pip

Você nunca deve usar o sudo com o pip3. Se você tem que usar o sudo - algo não está certo.
