问题描述

如果某些条件为假，我正在寻找一种退出 rpm 安装的方法.我在 %pre 部分添加了一个小脚本，如果我的条件失败，它会退出安装.

I am looking for a way to exit rpm install if some condition is false. I have added a small script in the %pre section that exits install if my condition fails.

我面临的问题是我看到 %pre scriptlet 被执行，并且 rpm 安装失败.然而，在它的最后，我得到了这 2 行我不想要的 -- Installed ... 其次是 Complete！

The problem I am facing is I see that the %pre scriptlet is executed, and rpm install does fail. Yet at the end of it I get these 2 lines which I don't want -- Installed ... followed by Complete!

推荐答案

如果你需要这个只是为了确保文件系统中有某个文件，你可以做简单的

If you need this just to make sure there is certain file in the filesystem, you can do simple

Requires: /path/to/expected/file

否则你可能真的不走运.

Otherwise you are indeed out of luck probably.

我可以想到非常丑陋的解决方案，包括从 scriptlet 中杀死 rpm，但那是万恶的 :-)

I could think of extremely ugly solution that would involve killing rpm from within scriptlet, but that is beyond evil :-)
