Linux—yum安装python-pip
centos下安装pip时失败：
[root@wfm ~]# yum -y install pip
Loaded plugins: fastestmirror, refresh-packagekit, security

Setting up Install Process
No package pip available.
Error: Nothing to do
解决方法：
需要先安装扩展源EPEL。
EPEL(http://fedoraproject.org/wiki/EPEL) 是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。
首先安装epel扩展源：
sudo yum -y install epel-release
如果，出现问题可以卸载重装epel-release：
然后再安装pip
~]# sudo yum -y install python-pip

如果安装报错：pip安装pkg_resources.DistributionNotFound: pip==9.0.1 #参考：https://blog.csdn.net/daiyutage/java/article/details/69945850
执行pip命令报错
Traceback (most recent call last):

pkg_resources.DistributionNotFound: pip==9.0.1
应该是缺少pip9.0.1
执行easy_install pip==9.0.1又报错

再安装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
再次安装pip9.0.1
easy_install pip==9.0.1
安装成功
