自用升级centos7.2的默认Python 2.7.5为python3.8

wget https://www.python.org/ftp/python/3.8.8/Python-3.8.8.tgz

tar zxvf Python-3.8.8.tgz

进入刚刚解压后的目录

./configure --prefix=/data/soft/python3

按照上面截图所属，需要安装gcc

安装报错需要安装

sudo yum install zlib1g-dev

make -j4
make install -j4

更换旧的python软连

unlink python
rm -rf /usr/bin/python
ln -s /data/soft/python3/bin/python3.8 /usr/bin/python
ln -s /data/soft/python3/bin/pip3.8 /usr/bin/pip

python -v
