升級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> parse_requirements(__requires__), Environment() 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
解決方法：
重新安裝pip
curl -O https://pypi.python.org/packages/source/p/pip/pip-7.1.2.tar.gz 用wget下載時會報錯，這里改用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 #創建軟鏈接時報文件已經存在時執行rm -rf /usr/bin/pip //pip默認安裝到了/usr/local/python27/bin下面
測試pip
[root@localhost pip-7.1.2]# pip list
distribute (0.6.14)
pip (7.1.2)
setuptools (0.6rc11)
wheel (0.29.0)
