Linux下安装Python3.6和第三方库

Posted 2020-10-13

一、安装Python-3.6.2.tgz

1. 安装依赖环境

最小化安装Redhat6.4环境下

yum -y install    gcc make zlib-devel bzip2-devel  ncurses-devel  readline-devel

(yum -y install  gcc make zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel db4-devel gdbm-devel  libpcap-devel xz-devel）

2.mkdir -p /usr/local/python3.6

3.编译安装

tar -zxvf Python-3.6.2.tgz

cd Python-3.6.2

./configure --prefix=/usr/local/python3.6

make

make install

4.设置python3.6为默认python命令，并设置yum的配置

cd /usr/bin

mv python pythonold

vi yum

将#!/usr/bin/pythono改成#!/usr/bin/pythonold

ln -s /usr/local/python3.6/bin/python3.6  python

二、安装第三方库

注：python3默认已经安装，使用方法如下：

ln -s /usr/local/python3.6/bin/easy_install-3.6 /usr/bin/easy_install

ln -s /usr/local/python3.6/bin/pip3.6 /usr/bin/pip

pip install pyreadline

easy_install pyreadline

-----------------------------------

1、安装setuptools-19.6.tar.gz

tar -zxvf setuptools-19.6.tar.gz

cd setuptools-19.6

python setup.py build

python setup.py install

2、安装pip-8.0.2.tar.gz

tar -zxvf pip-8.0.2.tar.gz

cd pip-8.0.2

python setup.py build

python setup.py install
