linux安装python

**linux 下安装 python 环境(未完成） **


首先python 官网下载 python 包（tgz文件）
mkdir  /usr/local/python3   新建文件夹
tar -xvzf  Python-3.7.1.tgz   解压文件
cd Python-3.7.1/              进入目录
./configure --prefix=/usr/local/python3 /usr/bin/python3   编译安装
make
make install
ln -s /usr/local/python3/bin/python3 /usr/bin/python3   建立python 软链接
执行下面两个命令，把path添加进去
vim ~/.bash_profile
.bash_profile


# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
export PATH
