Linux 下python 环境的安装

一、python环境的安装

1、安装必要的构建工具和库

sudo yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel

2、下载python3.8的源代码

wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz

3、解压下载的源码包

tar xvf Python-3.8.0.tgz

4、编译安装

./configure --prefix=/usr/local/python3.8
make && make install

• –prefix 指定安装的目录

5、创建软链接

ln -s /usr/local/python3.8/bin/python3 /usr/bin/python3
ln -s /usr/local/python3.8/bin/pip3 /usr/bin/pip3

6、配置环境变量

vim .bash_profile
export PYTHON_HOME=/usr/local/python3.8
export PATH=$PYTHON_HOME/bin:$PATH

7、生效验证

source ~/.bash_profile
echo $PYTHON_HOME
