本文主要介绍在Centos7系统上如果安装编译指的Python版本，本例安装Python-3.6.1
首先，为系统安装所需的依赖库，可根据具体使用情况安装，如：yum install -y gcc zlib zlib-devel openssl-devel bzip2-devel openssl-devel sqlite-devel ncurese-devel
下载源码包：wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz
解压安装：# xz -d Python-3.6.1.tar.xz
# tar -xvf Python-3.6.1.tar
# cd Python-3.6.1/
# ./configure --prefix=/usr/local/python3 --enable-optimizations
# make && make install
创建命令软链接：# ln -s /usr/local/python3/bin/python3.6 /usr/bin/python3
# ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
安装相应模板，根据需要安装，如：pip3 install pymysql
pip3 install requests
pip3 install PyQuery
如果出现如下提示：You are using pip version 9.0.1, however version 18.0 is available.You should consider upgrading via the 'pip install --upgrade pip' command.
表可pip版本过低，可执行命令升级：# pip3 install --upgrade pip
