centos6.7 安装python2.7、pip2.7、easy_install-2.7的方法

安装pip是真的恶心，搞了两天，终于在如下网站上看到一篇才得以解决

依赖

yum groupinstall -y Development tools

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

安装Python2.7

wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz

tar xvf Python-2.7.11.tgz

cd Python-2.7.11

./configure --prefix=/usr/local

make && make install && echo OK

安装完后的Python的可执行文件目录是 /usr/local/bin
安装完后的python安装目录路径是 /usr/local/lib/python2.7

检查安装python2.7是否成功

python -V

安装 setuptools(easy_install-2.7)

# 下载setuptools,easy_install 的安装包

wget https://bootstrap.pypa.io/ez_setup.py

#安装easy_install-2.7

python2.7 ez_setup.py

#安装完成后/usr/local/bin/目录下出现easy_install-2.7

安装pip2.7

#安装pip2.7

easy_install-2.7 pip

#安装完成后/usr/local/bin/目录下出现pip2.7

#升级pip2.7版本

pip2.7 install --upgrade pip

至此，pip2.7已经安装完成，可以通过pip2.7下载其它依赖包，格式如下：

pip2.7 install dlib

pip2.7 install numpy

注意：安装dlib前要先安装如下依赖

pip install boost

pip install cmake

pip install dib
