linux下安装python3

准备编译环境（避免产生各种问题）

yum grouplistyum groupinstall 'Development Tools'yum install zlib-devel bzip2-devel  openssl-devel ncurses-devel

下载 Python3.6代码包

wget  https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tar.gz

解压

tar xvf  Python-3.6.0.tar.gz

编译并安装

cd Python-3.6.0  #切到该目录下./configure --prefix=/usr/local/python3 #生成makefile文件make && make install

做软链：

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