**所有rpm包安装完成**

**4.测试python2.7是否可用**

![70 3][]

**python命令正常**

**3.测试yum是否可用**

\[root@mail yum\_and\_python2.7\]\# yum

![70 4][]

**yum命令正常**

**至此完全安装python2.7及yum完成！！**

**====================================**

**1.如果centos版本不是7.5，你需要下载对用的rpm包：**

**下载地址：http://mirrors.163.com/centos/7.x.xx/os/x86\_64/Packages/**

**2.如果安装过程中报错如 "aaa" is needed by "bbb" 则需先下载并安装对应的安装包aaa.rpm：**

error: Failed dependencies:  
dbus-python(x86-64) = 1.1.1-9.el7 is needed by dbus-python-devel-1.1.1-9.el7.x86\_64  
pkgconfig(dbus-1) >= 1.0 is needed by dbus-python-devel-1.1.1-9.el7.x86\_64
