Como instalo scipy com pip3 ? Se não houver nenhuma solução com pip3 , de que outra forma posso instalar o scipy para python3.x?

    

Answer 1

Ele está dizendo exatamente o que você precisa fazer: instalar todas as dependências de compilação.

Antes de eu chegar lá, eu já disse algumas vezes que eu geralmente não recomendo que as pessoas usem pip (ou pip3 ) para instalar pacotes em sua instalação global do Python. Ambos pip e apt-get são completamente alheios um ao outro. Arquivos podem ser indevidamente sobrescritos ou removidos e porque muito do seu sistema operacional depende do seu ambiente em Python, mexer com ele não é uma boa idéia.

Por isso, recomendo usar um virtualenv (onde você mantém tudo separado do sistema) ou apenas usar pacotes implantados no repositório.

Dito isto, a razão técnica que você não pode instalar é porque o SciPy precisa compilar uma carga de coisas e tem dependências externas para muito disso. Estes precisam ser cumpridos. Você poderia fazer isso manualmente (lendo o erro) ou, neste caso, onde há uma versão do repo, você poderia pedir ao Apt para instalar as dependências de compilação:

sudo apt-get build-dep python3-scipy

E isso instalará uma carga de pacotes métrica. Observe que alguns deles provavelmente serão coisas com as quais você já se encaixou com pip . Eu estou vendo muitas coisas complicadas. Cuidado.

Você ainda precisaria passar por um processo semelhante se estivesse criando um virtualenv, mas eu recomendaria não usar apt para atender suas dependências, porque você provavelmente terá versões diferentes de dependências. Isso não é uma receita de construção saudável.

Em resumo, usar a versão do repo é mais fácil.
