CentOS7安装Python3.7

首先安装依赖包，centos里面是-devel，如果在ubuntu下安装则要改成-dev，依赖包缺一不可，笔者曾安装python3未成功就是因为没有安装libffi-devel

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

然后获取python3.7的安装包

wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz

解压

tar -xvJf  Python-3.7.0.tar.xz

配置python3的安装目录并安装

cd Python-3.7.0
./configure --prefix=/usr/local/bin/python3
make
make install

创建软链接

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

出现上面就表示成功!!!
