    1.更换源文件

    vi /etc/apt/sources.list
    
    deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
     
    deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
     
    deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
     
    deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
     
    deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
    

    2.安装pyenv

    sudo apt install git
    git clone https://github.com/yyuu/pyenv.git ~/.pyenv
    

    vim更改~/.bashrc

    export PATH=~/.pyenv/bin:$PATH
    export PYENV_ROOT=~/.pyenv
    eval "$(pyenv init -)"
    

    完成之后

    source ~/.bashrc
    

    pyenv的下载源更改为国内源

    cd .pyenv/plugins/python-build/share/python-build
    

    找到你要下载的版本,这里以3.8.1为例
    https://www.python.org/ftp换成http://mirrors.sohu.com,如下

    #require_gcc
    prefer_openssl11
    export PYTHON_BUILD_CONFIGURE_WITH_OPENSSL=1
    install_package "openssl-1.1.0j" "https://www.openssl.org/source/old/1.1.0/openssl-1.1.0j.tar.gz#31bec6c203ce1a8e93d5994f4ed304c63ccf07676118b6634edded12ad1b3246" mac_openssl --if has_broken_mac_openssl
    install_package "readline-8.0" "https://ftpmirror.gnu.org/readline/readline-8.0.tar.gz#e339f51971478d369f8a053a330a190781acb9864cf4c541060f12078948e461" mac_readline --if has_broken_mac_readline
    if has_tar_xz_support; then
      install_package "Python-3.8.1" "http://mirrors.sohu.com/python/3.8.1/Python-3.8.1.tar.xz#75894117f6db7051c1b34f37410168844bbb357c139a8a10a352e9bf8be594e8" ldflags_dirs standard verify_py38 copy_python_gdb ensurepip
    else
      install_package "Python-3.8.1" "http://mirrors.sohu.com/python/3.8.1/Python-3.8.1.tgz#c7cfa39a43b994621b245e029769e9126caa2a93571cee2e743b213cceac35fb" ldflags_dirs standard verify_py38 copy_python_gdb ensurepip
    fi
    

    安装3.8.1

    pyenv install -v 3.8.1
    

    碰到问题:ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib? 解决方法如下:

    sudo apt-get install -y build-essential libssl-dev zlib1g-dev libbz2-dev \
    libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
    xz-utils tk-dev libffi-dev liblzma-dev python-openssl git
    

    成功了!
