Linux下安装Python3.6

1. 安装依赖环境

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

2.下载Python3
　　https://www.python.org/downloads/

# wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz

3.安装python3

　　我个人习惯安装在/usr/local/python3（具体安装位置看个人喜好）
　　创建目录：

# mkdir -p /usr/local/python3

解压下载好的Python-3.x.x.tgz包

# tar -zxvf Python-3.6.1.tgz

4.进入解压后的目录，编译安装。

# cd Python-3.6.1
# ./configure --prefix=/usr/local/python3

按ESC，输入:wq回车退出。

修改完记得执行行下面的命令，让上一步的修改生效：

# source ~/.bash_profile

检查Python3及pip3是否正常可用：

# python3 -V
Python 3.6.1
# pip3 -V
pip 9.0.1 from /usr/local/python3/lib/python3.6/site-packages (python 3.6)

修改python默认为python3

sudo rm /usr/bin/python
sudo ln -s /usr/local/bin/python3.4 /usr/bin/python
