使用 yum 安装 python-devel

Question

我正在尝试使用python-devel以下方式安装yum：

sudo yum install python-devel

并得到以下内容：

Resolving Dependencies

--> 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

然而它输出：

Package matching python-2.7.5-76.el7.x86_64 already installed. Checking for update.
Nothing to do

我应该怎么办？

如果我跑：sudo yum info python，它给了我：

Description : Python is an interpreted, interactive, object-oriented programming

            : dynamic typing. Python supports interfaces to many system calls and

            : Mac and MFC).
            : 
            : Programmers can write new built-in modules for Python in C or C++.
            : Python can be used as an extension language for applications that need
            : a programmable interface.

您可以在后缀中指定 arch，这对我有用：

sudo yum install python3-devel.x86_64
