比如，在安装软件时缺少相应的依赖包，如

libnautilus-extension

如果直接使用

yum install libnautilus-extension

也许没有，但可以使用如下命令找到

 

[glenn@coolhand ~]$ yum whatprovides */libnautilus-extensionLoaded plugins: fastestmirror, presto, refresh-packagekitrpmfusion-nonfree-updates/filelists_db                                            |  25 kB     00:00     updates/filelists_db                                                              | 4.9 MB     00:03     nautilus-devel-2.26.3-1.fc11.i586 : Support for developing nautilus extensionsRepo        : fedoraMatched from:Filename    : /usr/include/nautilus/libnautilus-extensionnautilus-devel-2.26.3-2.fc11.i586 : Support for developing nautilus extensionsRepo        : updatesMatched from:Filename    : /usr/include/nautilus/libnautilus-extension

这时候就知道要用这个命令去安装：

yum install nautilus-devel

这样就可以安装成功了。
