操作系统：vm centos6.5 64
1.当前的python版本为2.6.6
python -V Python 2.6.6
2.下载python2.7.6
wget http://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz
3.解压python
tar -jxvf Python-2.7.6.tar.bz2
发现没有bzip2软件包
yum install bzip2
4.安装
cd Python-2.7.6 && ./configure 没有gcc支持：error: no acceptable C compiler found in $PATH
安装gcc
yum install gcc
继续安装python
./configure && make all && make install && make clean && make distclean
5.建立软连接
mv /usr/bin/python /usr/bin/pythonh2.6.6 ln -sv /usr/local/bin/python2.7 /usr/bin/python
6.查看当前python的版本
python -V Python 2.7.6
7.当你尝试yum的时候
yum list | grep python There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named yum Please install a package which provides this module, or verify that the module is installed correctly. It‘s possible that the above module doesn‘t match the current version of Python, which is: 2.7.3 (default, Aug 1 2014, 18:27:15) [GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq
当系统centos6.5中的python软链接到python2.7.6后，yum与python2.7.6不兼容，要指定yum的python版本
vi /usr/bin/yum #将#!/usr/bin/python改为#!/usr/bin/python2.6.6 #或者是 sed -i ‘s/python/python2.6.6/‘ /usr/bin/yum
8.既然都已经升级了python，顺带就安装pip
安装setuptools
wget https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev tar zxvf default.tar.gz cd pypa-setuptools-60d0c9f24d88/ python setup.py install
安装pip
wget https://pypi.python.org/packages/source/p/pip/pip-1.5.tar.gz --no-check-certificate tar zxvf pip-1.5.tar.gz cd pip-1.5 python setup.py install
centos下python版本升级为2.7.6
