Como posso instalar o ipython com o pip3?

Question

Acabei de fazer 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?

    

Answer 1

Você pode não ter permissão de gravação no diretório /usr/local/bin . Para contornar isso, corra

sudo pip3 install ipython

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

    

Answer 2

Você usa --user , a menos que você esteja instalando como superusuário (su) por algum motivo.

pip3 install --user ipython
