CentOS 7下安装python3
1. 安装python3
1.下载安装包:
wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
2.安装必要的一些依赖包:
yum -y install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel zlib-devel
3.解压,编译,安装
tar -zxvf Python-3.6.3.tgz #解压
cd Python-3.6.3 #进入解压后的目录
./configure --prefix=/usr/local/python3 (prefix表示安装的路径,我安装在/usr/local中,也可以安装其他地方) #编译
make && make install #安装
4.创建python3的软连接
ln -s /usr/local/python3/bin/python3.6 /usr/bin/python3 (软连接的文件名不要用python,因为python已经指向了python2.7)
5.创建pip3的软连接
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
