python安装及虚拟化环境创建

python 安装

依赖环境准备

yuminstall -y gcc yuminstall -y zlib*yuminstall -y openssl openssl-develyum-y install libffi-devel

获取python包

wget [https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz](https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz)

配置

./configure --prefix=/usr/local/lib/python3.6.6 --with-ssl

编译安装

make&&make install

更换 pip 源

mkdir ~/.pip

echo'[glolbal]'>>~/.pip/pip.conf

echo'index-url = https://mirrors.aliyun.com/pypi/simple'>>~/.pip/pip.conf

QA

• 报mysql_config not fund

• 解决

yuminstall mysql-devel gcc gcc-devel python-devel

虚拟化环境

安装

pipinstall virtualenvpipinstall virtualenvwrapper

创建虚拟化环境

virtualenv  --no-site-packages --python=python3.6  /app/virtual/
## 进入虚拟化huanjing
source   /app/virtual/bin/activate
## 退出虚拟化环境
deactive

注

使用virtualenv --version，看到自己的版本大于20，就可以将如下这段删除 --no-site-packages
