### 1.安装 python3.7.4 ###

###### 1》安装python3.7.4的依赖软件 ######

sudo apt update
    sudo apt install -y make build-essential libssl-dev zlib1g-dev
    sudo apt install -y libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm
    sudo apt install -y libncurses5-dev libncursesw5-dev xz-utils tk-dev
    sudo apt-get install libffi-dev #安装　libffi-devel

*  如果不安装 libffi-devel 会报如下错误（注意 ubuntu，debian 和 deepin 环境对应的 libffi-devel 是 libffi-dev）：

ModuleNotFoundError: No module named '_ctypes'
    Makefile:1142: recipe for target 'altinstall' failed
    make: *** [altinstall] Error 1

###### 2》下载Python-3.7.4.tgz包并编译安装 ######

*  在终端中运行以下命令下载源码包，（如果下载速度慢，可以用浏览器或者迅雷下载）或到 https://www.python.org/downloads/ 下载。

wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz

*  从压缩包解压Python-3.7.4.tgz源代码：

tar xvf Python-3.7.4.tgz

*  安装方法一

# 进入目录
    cd Python-3.7.4
    # 运行./configure 配置文件开始构建
    ./configure --enable-optimizations
    # 运行以下命令编译安装
    make -j8 && sudo make altinstall
    sudo make clean

*  安装方法二，

# 1.创建目录
    mkdir -p /usr/local/python3.7.4
    # 2.进入目录
    cd Python-3.7.4
    # 3.运行./configure 配置文件开始构建
    ./configure --prefix=/usr/local/python3.7.4
    #/usr/local/python3.7.4为上面步骤创建的目录
    # 4.运行以下命令编译安装
    make && make install
    sudo make clean
    # 5.建立Python3和pip3的软链:
    ln -s /usr/local/python3.7.4/bin/python3 /usr/bin/python3.7.4
    ln -s /usr/local/python3.7.4/bin/pip3 /usr/bin/pip3.7.4
    # 6.并将/usr/local/python3.7.4/bin加入PATH
    vim /etc/profile

/etc/profile 文件中添加如下内容

# User specific environment and startup programs
    PATH=$PATH:$HOME/bin:/usr/local/python3.7.4/bin
    export PATH

*  至此，Python 3.7.4已经安装完成，你可以在终端中使用python3.7.4了

root@wdh:/home/wdh/Downloads/Python-3.7.4# python3.7.4
    Python 3.7.4 (default, Apr 14 2020, 02:00:30)
