tar zxvf Python-3.6.0.tgz
新建一个目录用于存放安装的Python3.6
cd Python-3.6.0
mkdir /usr/local/python36
配置安装路径
./configure --prefix=/usr/local/python36
编译Python3.6
make
编译安装
make install
报错情况1的解决办法
zipimport.ZipImportError: can’t decompress data; zlib not available
执行：yum -y install zlib*

make install
看到下面这句说明安装成功了
