rpmforge（RHEL）上没有emacs软件包

Question

尝试在RHEL 5.5上安装emacs时，出现以下错误：

 $ sudo yum install emacs
 Loaded plugins: rhnplugin, security
 This system is not registered with RHN.
 RHN support will be disabled.
 Setting up Install Process
 No package emacs available.
 Nothing to do

我已经安装了rpmforge。 当我尝试搜索emacs时，得到以下信息：

================================================= Matched: emacs ==================================================
crm114-emacs.x86_64 : Emacs mode for CRM114
ed.x86_64 : The GNU line editor.

在哪里可以找到emacs？ （或者我是否必须从源代码下载并编译？）谢谢

由于您正在运行RHEL，因此需要通过rhn_register命令向RedHat注册系统。 有关如何执行此操作的更多详细信息，请参见http://docs.redhat.com/docs/zh-CN/Red_Hat_Network_Satellite/5.4/html/Reference_Guide/ch-register.html 。

完成此操作后，您可以成功使用yum update ， yum install ...等。
