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
