linux安装python3环境并配置虚拟环境，,1.安装必要库yum

1.安装必要库

yum -y install gccyum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel

2.下载python源码：https://www.python.org/downloads/source/

# 解压源码tar -zxvf Python-3.7.4.tgz # 建立一个空文件夹，用于存放python3程序　　　　　mkdir /usr/local/python3# 执行配置文件，编译，编译安装cd Python-3.7.4./configure --prefix=/usr/local/python3make && make install# 建立软连接　　　　　　　　　　　　　　　　　　　　　ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip3

3.测试python3和pip3

python3pip3 --version

4.配置虚拟环境

# 安装virtualenvpip3 install virtualenv -i https://pypi.douban.com/simple/# 安装virtualenvwrapperpip3 install virtualenvwrapper -ihttps://pypi.douban.com/simple/# 配置环境变量vim /etc/bashrc,插入以下代码：export WORKON_HOME=/data/virtualenv # 虚拟环境存放目录export VIRTUALENVWRAPPER_VIRTUALENV_ARGS=‘--no-site-packages‘#创建纯净环境export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 # python3source /usr/local/python3/bin/virtualenvwrapper.sh# 使环境变量立即生效source /etc/bashrc# 测试workonmkvirtualenv testrmvirtualenv test
