CentOS7下安装Python3.7、

CentOS7默认已经安装了Python2.7，现安装3.7和它并存

一、安装依赖

yum -y groupinstall "Development tools"

若出现以下错误：No packages in any requested group available to install or update

解决方法：

cd /etc/yum.repos.d  
sudo wget http://public-yum.oracle.com/public-yum-el5.repo

cd /etc/pki/rpm-gpg/  
sudo wget https://public-yum.oracle.com/RPM-GPG-KEY-oracle-el5

然后重试即可

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

yum install -y libffi-devel zlib1g-dev

yum install zlib* -y

二、下载解压

cd /tmp

wget wget https://www.python.org/ftp/python/3.7.2/Python-3.7.2.tar.xz

tar -xvJf Python-3.7.2.tar.xz

三、创建编译安装目录

mkdir /usr/local/python3

四、安装

cd Python-3.7.2

./configure --prefix=/usr/local/python3 --enable-optimizations --with-ssl

make && make install

五、建立软链接

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

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

六、验证

python3 -V

pip3 -V

Done.
