RedHat离线安装Python3以及各种依赖

1, yum install -y ncurses-libs zlib-devel mysql-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的源文件包
    ./configure
    make
    make install
    这时应该可以默认安装了pip3

3, 在有网络的环境下，
    pip3 freeze > require.txt  # 
    pip3 download -r require.txt -d packages

4, 在没有网络的情况下，
    cd packages
    pip3 install xxx.whl
    pip3 install xxx.tar.gz
    使用 pip3 install -r require.txt --root packages 无效
