升级python到2.7版本pip不可用
[root@localhost pip-7.1.2]# pip
Traceback (most recent call last):
File "/usr/bin/pip", line 5, in <module>
from pkg_resources import load_entry_point
File "/usr/local/python27/lib/python2.7/site-packages/distribute-0.6.14-py2.7.egg/pkg_resources.py", line 2675, in <module>

File "/usr/local/python27/lib/python2.7/site-packages/distribute-0.6.14-py2.7.egg/pkg_resources.py", line 552, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pip==7.1.0
解决方法：重新安装pip
curl -O https://pypi.python.org/packages/source/p/pip/pip-7.1.2.tar.gz
用wget下载时会报错，这里改用curl -O
tar zxvf pip-7.1.2.tar.gz
cd pip-7.1.2
python setup.py install
ln -s /usr/local/python27/bin/pip2.7 /usr/bin/pip #创建软链接时报文件已经存在时执行rm -rf /usr/bin/pip
//pip默认安装到了/usr/local/python27/bin下面
