1、CentOS6.5 安装Python 的依赖包
yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel2、下载Python3.5的源码包并编译
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0.tgz
tar xf Python-3.5.0.tgzcd Python-3.5.0
./configure --prefix=/usr/local --enable-shared make make install ln –s /usr/local/bin/python3 /usr/bin/python33、在运行Python之前需要配置库:
echo /usr/local/lib >> /etc/ld.so.conf.d/local.conf
ldconfig4、运行演示:
python3 --version
Python 3.5.05、删除编译Python时所需要的库
yum groupremove "Development tools" --remove-leaveas
yum remove zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel --remove-leaves6、设置别名方便使用
alias py=python3
------------------------------------------------------------------------------- Python库管理程序: pip安装pip:
yum install python-pip 如果出现 'No package python-pip available.' 则需要先安装yum的扩展源 yum -y install epel-release支持多python版本共存: pip(pip2) pip3
显式已安装包列表:
pip list pip list --forma=columns 安装指定包: pip install xxx 安装指定版本的包: pip install 'xxx>2.0' pip install 'xxx>2.0,<3.0' 卸载包: pip uninstall xxx 更新包: pip install --upgrade xxx 更新自己: pip install --upgrade pip
