tar -xvJf  Python-3.7.0.tar.xz

3.编译安装

mkdir /usr/local/python3 #创建编译安装目录
cd Python-3.7.0
./configure --prefix=/usr/local/python3
make && make install

4.创建软连接

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

5.验证是否成功

python3 -V
pip3 -V

# 卸载python3
