我正试图通过Yum在CentOS 5.3.3上安装Mono。
根据我在别处找到的说明，我从Mono网站上抓取了 mono.repo 的副本，并将其放在/etc/yum.repos.d目录中。
该文件如下所示：
[mono]
name=Mono for rhel-4-i386 (stable)
baseurl=http://ftp.novell.com/pub/mono/download-stable/rhel-4-i386/
enabled=1
gpgcheck=0
接下来我运行 yum install mono-complete ，这是日志。

根据this post on the CentOS forums，我甚至启用了 centosplus 回购 - 但没有用。
有人可以指导我解决 libexif.so.9 缺少的依赖关系吗？我似乎无法找到这个确切版本的转速......
谢谢， 米^ E
答案 0 :(得分：1)
修改： 我刚刚意识到你正在使用CentOS 4源，但试图在CentOS 5上安装。这几乎肯定是你的问题。无论如何，为了所有人的利益，我在下面留下原来的答案。
我同意这是ServerFault的事情：
yum install libexif
或
yum install exif
更重要的是，我肯定会自己编译Mono，以便您可以使用更新的东西。这是一件轻而易举的事（一旦你特别安装了libgdiplus）。我在CentOS 5上做了很多次，在CentOS 4上做过几次。
http://ftp.novell.com/pub/mono/sources/
编译libgdiplus以支持System.Drawing：
$ tar xzf libgdiplus-2.10.tar.gz
$ cd libgdiplus-2.10
$ ./configure
$ make
$ make install
然后编译Mono本身：
$ tar xzf mono-2.10.tar.gz
$ cd mono-2.10
$ ./configure
$ make
$ make install
