centos下安裝pip時失敗：
[root@wfm ~]# yum -y install pip

Setting up Install Process
No package pip available.
Error: Nothing to do
解決方法：
需要先安裝擴展源EPEL。
EPEL(http://fedoraproject.org/wiki/EPEL) 是由 Fedora 社區打造，為 RHEL 及衍生發行版如 CentOS、Scientific Linux 等提供高質量軟件包的項目。
首先安裝epel擴展源：
sudo yum -y install epel-release
如果，出現問題可以卸載重裝epel-release：
然后再安裝pip
~]# sudo yum -y install python-pip

如果安裝報錯：pip安裝pkg_resources.DistributionNotFound: pip==9.0.1 #參考：https://blog.csdn.net/daiyutage/java/article/details/69945850
執行pip命令報錯
Traceback (most recent call last):
File "./pip", line 5, in <module>
from pkg_resources import load_entry_point
File "/opt/soft/distribute-0.7.3/pkg_resources.py", line 2989, in <module>

File "/opt/soft/distribute-0.7.3/pkg_resources.py", line 624, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: pip==9.0.1
應該是缺少pip9.0.1
執行easy_install pip==9.0.1又報錯
Traceback (most recent call last):
File "/usr/bin/easy_install", line 5, in <module>
from pkg_resources import load_entry_point

File "/opt/soft/distribute-0.7.3/pkg_resources.py", line 624, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: distribute==0.6.10
再安裝distribute包
wget http://pypi.python.org/packages/source/d/distribute/distribute-0.6.10.tar.gz
cd distribute-0.6.10
python setup.py install
再次安裝pip9.0.1
easy_install pip==9.0.1
