编译安装python3.6.1

如果本机安装了python2，尽量不要管他，使用python3运行python脚本就好，因为可能有程序依赖目前的python2环境，比如yum

 

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.安装python3

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

mkdir -p /usr/local/python3    #目录自行指定

tar xvf Python-3.6.1.tgz

cd Python-3.6.1/

./configure --prefix=/usr/local/python3 

make

make install

 

3.建立python3的软连接

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

 

4.将/usr/local/python3/bin加入PATH

# vim ~/.bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

. ~/.bashrc

fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:/usr/local/python3/bin    #添加这一步

export PATH

 

source ~/.bash_profile  #使文件生效

 

 

5.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)

 

 

6.不行的话在创建一下pip3的软链接

ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
