  • Linux手工安装官方Python3.5

    1.安装相关依赖库(工具包)

    yum install gcc patch libffi-devel python-devel  zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel -y

    2.下载python3的源代码(在linux终端下输入命令)

    # 切换/opt目录
    
    cd /opt
    
    # 下载python3.5.6源代码
    
    wget https://www.python.org/ftp/python/3.5.6/Python-3.5.6.tgz
    
    # python源码的下载地址。(全都在这了)https://www.python.org/ftp/python/

    3.解压缩源代码

    tar -xf Python-3.5.6.tgz
    
    (出现Python-3.5.6)

    4.切换python3.5的源代码目录

    cd Python-3.5.6

    5.生成编译脚本(指定安装目录)

    ./configure --prefix=/opt/python35

    6.编译

    make

    7.编译成功后,编译安装

    make install

    8.切换已经装好的python3.5目录

    cd /opt/python35/

    9.查看python3.5的可执行脚本文件

    [root@localhost python35]# ls bin/

    10.执行python3.5解释器

    1.绝对路径执行方式一
    
    /opt/python35/bin/python3.5
    
    2.相对路径执行方式二
    
    [root@localhost python35]# bin/python3.5
    
    3.添加环境变量
    
    1.添加软连接(用法)
    
    ln -s 原文件路径 目标文件路径
    
    2.添加软连接
    
    (绝对路径)ln -s /opt/python35/bin/python3.5 /usr/local/bin/python3
    
    4.添加pip3软连接
    
    ln -s /opt/python35/bin/pip3 /usr/local/bin/pip3
    
     
    5.查看pip3版本
    
    pip3 -V
    
    pip 10.0.1 from /opt/python35/lib/python3.5/site-packages/pip (python 3.5)
    TIP:
    
    #python3.5软连接:
    
    ln -s /opt/python35/bin/python3.5 /usr/local/bin/python3.5
    
     
    #删除python3.5的软连接:
    
    rm -rf /usr/local/bin/python3
