一台新服务器centos6.7安装pip。

163的centos源并没有这个，用了一个python源，版本不兼容

报错：

Error: Package: python-argparse-1.3.0-48.8.x86_64 (python)

           Requires: python = 2.6            Installed: python-2.6.6-66.el6_8.x86_64 (@updates)                python = 2.6.6-66.el6_8            Available: python-2.6.6-64.el6.x86_64 (base)                python = 2.6.6-64.el6 Error: Package: python-setuptools-28.3.0-86.1.x86_64 (python)            Requires: update-alternatives Error: Package: python-setuptools-28.3.0-86.1.x86_64 (python)            Requires: python-xml  You could try using --skip-broken to work around the problem ** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows: python-libs-2.6.6-66.el6_8.x86_64 is a duplicate with python-libs-2.6.6-64.el6.x86_64

或者报错：

Error: Package: python-pip-9.0.1-1.2.x86_64 (python)

           Requires: python-xml Error: Package: python-argparse-1.3.0-48.8.x86_64 (python)            Requires: python = 2.6            Installed: python-2.6.6-66.el6_8.x86_64 (@updates)                python = 2.6.6-66.el6_8            Available: python-2.6.6-64.el6.x86_64 (base)                python = 2.6.6-64.el6 Error: Package: python-pip-9.0.1-1.2.x86_64 (python)            Requires: update-alternatives  You could try using --skip-broken to work around the problem

 You could try running: rpm -Va --nofiles --nodigest

使用--skip-broken也不行

然后：查到要用epel安装扩展包

yum -y install epel-release

接下来

yum -y install python-pip

OK~

EPEL是fedora项目中linux企业版扩展包
