Python 3.6 Centos 7¶

Varias formas para tener ultima version de Python 3 en Centos 7.

Compilando fuentes¶

Nota

Con la version 3.6 no lo he probado.

Post instalación Centos 8

sudo yum install \
    zlib-devel \
    bzip2-devel \
    openssl-devel \
    ncurses-devel \
    sqlite-devel \
    readline-devel \
    tk-devel \
    gdbm-devel \
    db4-devel \
    libpcap-devel \
    xz-devel

sudo echo "/usr/local/lib" >> /etc/ld.so.conf

wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
tar -zxvf Python-3.6.3.tgz
cd Python-3.6.3

./configure --prefix=/usr/local --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"
make
sudo make altinstall

iuscommunity¶

yum -y install yum-utils

yum -y install https://centos7.iuscommunity.org/ius-release.rpm
yum -y install python36u python36u-pip python36u-devel

software collections¶

Esta forma no la conozco bien, ademas virtualenvwrapper no he conseguido instalarlo, aunque si virtualenv.

¿Para un servidor de producción, quiza virtualenvwrapper no sea del todo necesario?

yum install centos-release-scl
yum-config-manager --enable rhel-server-rhscl-7-rpms
yum install rh-python36
scl enable rh-python36 bash

Me falta probarlo mas…

Python 3.4 epel¶

yum install epel-release

yum install python34 python34-setuptools python34-devel redhat-rpm-config

curl https://bootstrap.pypa.io/get-pip.py | python3.4

Virtualenvwrapper¶

Como usuario:

pip3.6 install --user virtualenvwrapper

Editar .bashrc

which python3.6
which virtualenvwrapper.sh

vim ~/.bashrc

# Virtualenvwrapper
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
export WORKON_HOME=$HOME/.virtualenvs
source ~/.local/bin/virtualenvwrapper.sh

source ~/.bashrc

Comandos virtualenvwrapper¶

mkvirtualenv Crea un nuevo virtualenv
rmvirtualenv Elimina un virtualenv existente
workon Cambia el actual virtualenv
deactivate Desactivar virtualenv
lsvirtualenv Listar virtualenvs
