linux(centos或ubuntu)编译安装python3

linux 编译安装python3

1.红帽系/red/centos

1. 安装依赖包：

   yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel

2. 官网下载源码：

   https://www.python.org/downloads

   https://www.python.org/downloads/release/python-375/

3. 解压：

   tar -xzvf Python-3.7.3.tgz

4. 编译安装

   # 配置， 检查安装环境， 配置安装目录， 生成Makefile文件
   -  sudo ./configure --prefix=/opt/python/python-3.7.5    
   # 添加到环境变量 
   -  sudo ./configure --enable-optimizations    
   # 编译和安装	
   -  sudo make && sudo make install
   -  如果编译失败就 make distclean 然后重新编译 
              

5. 卸载：

   在编译目录运行：
   	sudo  make  uninstall
              

2.debian/ubuntu系

1. 先安装依赖

   # 更新安装源
   sudo apt-get update
   # 安装依赖编译
   sudo apt-get install -y gcc make 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
              

2. … 后面的步骤和centos相同。
