centos5.6 安装 python

转自:http://blog.csdn.net/dqatsh/article/details/6592989

1. install python 2.7

refer: http://www.cnblogs.com/minglog/archive/2011/04/20/2022479.html

wget http://www.python.org/ftp/python/2.7.2/Python-2.7.2.tar.bz2

./configure

make

make install

rm /usr/bin/python

ln -s /usr/local/bin/python2.7 /usr/bin/python

*******************

发现yum不能用了，yum依赖python2.4, 处理如下：

vim /usr/bin/yum

将文件头部的

#!/usr/bin/python

改成

#!/usr/bin/python2.4

就可以继续使用yum了

*******************

2. install setuptools

wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg#md5=fe1f997bc722265116870bc7919059ea

sh setuptools-0.6c11-py2.7.egg

4. Tips

easy_install安装后如何删除 编辑 /usr/local/lib/python2.7/site-packages/easy-install.pth , 删除相应的行。删除相应的egg文件。 python -u -u     : unbuffered binary stdout and stderr; also PYTHONUNBUFFERED=x          see man page for details on internal buffering relating to '-u'
