【问题描述】：
我正在尝试使用yum 安装python-devel：
sudo yum install python-devel
并获得以下信息：
Resolving Dependencies
--> Running transaction check
---> Package python-devel.x86_64 0:2.7.5-76.el7 will be installed
--> Processing Dependency: python(x86-64) = 2.7.5-76.el7 for package: python-devel-2.7.5-76.el7.x86_64

python(x86-64) = 2.7.5-76.el7
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
我的理解是它需要这个特定版本的python：python-2.7.5-76.el7.x86_64，因此我尝试了：
sudo yum install python-2.7.5-76.el7.x86_64
但是输出：
Package matching python-2.7.5-76.el7.x86_64 already installed. Checking for update.
Nothing to do
我该怎么办？
如果我跑了：sudo yum info python，它给了我：

sudo yum downgrade <package_name>-<version_info>可能会有所帮助。更多信息在这里：shellhacks.com/yum-install-specific-version-of-package -
您是否禁用或删除了更新存储库？

@jordanm 这个命令是什么？

@SANTOSHKUMARDESAI 我试过你说的，得到了类似的错误说你需要
python-libs(x86-64) = 2.7.5-76.el7 -
