一、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/
|
1
|
# 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：
|
1
|
# mkdir -p /usr/local/python3 |
解压下载好的Python-3.x.x.tgz包(具体包名因你下载的Python具体版本不不同⽽而不不同，如：我下载的是Python3.6.1.那我这里就是Python-3.6.1.tgz)
|
1
|
# tar -zxvf Python-3.6.1.tgz |
4.进入解压后的目录，编译安装。
|
1
2
|
# cd Python-3.6.1# ./configure --prefix=/usr/local/python3 |
如果出现：no acceptable C compiler found in $PATH
那么说明需要安装gcc
yum install gcc
然后：./configure --prefix=/usr/local/python3
make
make install
5.建立python3的软链
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
6.并将/usr/local/python3/bin加入PATH
1 # vim ~/.bash_profile 2 # .bash_profile 3 # Get the aliases and functions 4 if [ -f ~/.bashrc ]; then 5 . ~/.bashrc 6 fi 7 # User specific environment and startup programs 8 PATH=$PATH:$HOME/bin:/usr/local/python3/bin 9 export PATH
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：
1 # python3 -V 2 Python 3.6.1 3 # pip3 -V 4 pip 9.0.1 from /usr/local/python3/lib/python3.6/site-packages (python 3.6)
7.不行的话在创建一下pip3的软链接
1 ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
