linux 安装Python3.6

1、安装依赖

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、下载安装包（可以Windows下载https://www.python.org/downloads/也可以用wget

wget -c https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz

下载tgz 包

3、新建一个Python的安装目录，mkdir /root/pyrhon36

4、进入tgz包的路径解压：tar -vxzf Python-3.6.1.tar.gz

5、解压完成，cd Python-3.6.1

6、指定Python的安装路径 ./configure --prefix=/root/python36

7、make

8、make install

9、因为Linux默认安装Python2，需要修改软链接：ln -s /root/python36/bin/python3.6  /usr/bin/python

10、修改pip的软链接：ln -s /root/python36/bin/pip3  /usr/bin/pip

11、配置环境变量 vim ~~/.bash_profile   编辑

PATH=$PATH:$HOME/bin:/root/python36/bin

export PATH

 

ps：修改软链接以后yum 使用报错，需要修改报错文件使用Python3
