ubuntu系统部署python3.6.4

Ubuntu的版本为16.04，系统自带的Python版本较低，使用亲本版本3.6.4，下为安装步骤：

一、官网下载Python3.6.4版本

　　新建目录：

sudo mkidr /usr/local/python3    

　　下载Python：

wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz

二、解压缩文件

cd /usr/local/python3  
sudo tar -xvf Python-3.6.4.tgz

三、编译配置

cd /usr/local/python3/Python-3.6.4

sudo ./configure --prefix=/usr/local/python3

五、安装

make
make install

 注：若出现

zipimport.ZipImportError: can't decompress data; zlib not available
Makefile:1079: recipe for target 'install' failed
make: *** [install] Error 1

等错误，需要安装依赖文件：

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

六、创建新版本软连接

sudo mv /usr/bin/python /usr/bin/python_bak
sudo ln -s /usr/local/python3/bin/python3 /usr/bin/python

检查版本：python -V

若出现Python 3.6.4则软连接配置成功
