centos7.5 安装 thefuck -- 小米实战

1. 安装前置依赖

    yum -y groupinstall "Development tools"
    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 libffi-devel

2. 确保原系统命令可以用

    vi /usr/bin/yum
    把#! /usr/bin/python修改为#! /usr/bin/python2
    同理 vi /usr/libexec/urlgrabber-ext-down 文件里面的#! /usr/bin/python 也要修改为#! /usr/bin/python2

3. 下载和安装

    wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz  //下载地址可以在官网找到
    tar -xvf  Python-3.6.2.tar.xz  //解压
    ./configure prefix=/usr/local/python3 // 配置安装路径
    make && make install // 编译和安装

4. 建立软链方便使用

    ln -s /usr/local/python3/bin/thefuck /usr/bin/thefuck
    ln -s /usr/local/python3/bin/fuck /usr/bin/fuck
    ln -s /usr/local/python3/bin/pip pip3
    ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3.7
    ln -s /usr/bin/python3.6 /usr/bin/python3

5. 添加到系统的软件版本控制器

    update-alternatives --install /usr/bin/pip pip /usr/bin/pip2 1  //添加PIP2
    update-alternatives --install /usr/bin/pip pip /usr/bin/pip3 2  //添加PIP3
    update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1   //添加python2
    update-alternatives --install /usr/bin/python python /usr/bin/python3.7 2   //添加python3
   
    update-alternatives --list  //查看清单
    update-alternatives --config python  //手动配置python pip同理
    update-alternatives --auto python  //自动配置python pip同理
