virtualenv gcc error MySQL-python

Question

Eu estou tentando instalar o MySQL-python através do PuTTY com virtualenv.

Especificações.
* CentOS-6.0
* Python2.6

Então eu li muitos sites e a maior coisa que eu vejo é python-dev e python-devel (btw eu não sei a diferença). Eu não consigo fazer isso para instalar, Sudo, yum, easy_install e pip são o que eu tentei. Eu não sou o administrador deste servidor tão sudo e yum não posso executar. Eu tive o administrador tentar instalar, ambos, no servidor dist. de python e meu virtualenv. Ambos dizem que não há nada para fazer. Aqui está o erro que eu recebo ao tentar instalar o MySQL-python-1.2.3

Desculpe, não consigo obter o erro completo no PuTTY

    

Answer 1

O arquivo README localizado na fonte do mysql-python declara os Pré-requisitos:

• Python 2.3.4 ou superior
• setuptools
• MySQL 3.23.32 ou superior (com muitas estipulações não vou postar)
• mysql-devel
• mysql
• zlib
• zlib-devel
• openssl
• gcc

Então, tente o seguinte:

yum -y install mysql-devel mysql zlib zlib-devel openssl

Em seguida, tente instalar novamente:

pip install mysql-python

( easy_install é depreciado em favor de pip , então acostume-se a usar isso)

E sem vergonha: aqui está uma rápida descrição em ambientes virtuais e um link para um mais completo . Dê uma olhada no script activate , e você verá que apenas preenche o caminho para o diretório ./bin/ para o seu $PATH , então você pode endereçar a mesma instância do python simplesmente antecipando o caminho para o binário.
