学习python3第一天：centos7同时安装python2,python3并安装pip,pip3

摘至别人博客，以后有用是查看：
最小化安装的Centos7 需要安装pip

yum install python-pip

没有的化可以先运行 yum install epel-release

版本查看 pip -V

先安装几个必要包python3 和pip3 用到

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

创建python3目录

mkdir /usr/local/python3 #类似Windows的安装目录

进入local 目录 cd /usr/local

wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz

解压命令 tar -xvf Python-3.6.5.tgz

进入解压文件夹配置安装目录

cd Python-3.6.5

./configure –prefix=/usr/local/python3

make

make install

配置python3 pip3 软链接

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

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

查看是否安装成功

python3 -V

pip3 -V
