centos7 安装 python3.7.3 环境

步骤1:安装依赖

yum install -y openssl-devel openssl-static zlib-devel lzma tk-devel xz-devel bzip2-devel ncurses-devel gdbm-devel readline-devel sqlite-devel gcc libffi-devel

 

步骤2.下载并安装python3.7.3

在/usr目录下创建文件夹Downloads
mkdir /usr/Downloads

切换到Downloads目录
cd /usr/Downloads

wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tgz

  
解压安装包
tar -xvf Python-3.7.3.tgz

将解压后文件夹迁移至 /usr/local
mv Python-3.7.3 /usr/local

进入Python目录
cd /usr/local/Python-3.7.3/

执行配置文件
./configure

编译安装
make
make install

在/usr/bin路径下生成python3的软链接
ln -s /usr/local/Python-3.7.3/python /usr/bin/python3

pip3为默认的不需要建立软连接
