如何从/usr/local 卸载 Ruby? [英] How to uninstall Ruby from /usr/local?

问题描述

一切都很好，直到我们决定将 ruby​​ 从 1.8.6 升级到 1.8.7，然后一切都崩溃了.当我们从源代码编译 Ruby 1.8.7 时，它被安装到/usr/local/bin 中，而 Ruby 1.8.6 则留在/usr/bin 中.目前，我们已经卸载了 ruby​​ 1.8.6，并且我们从/usr/local 中删除了 ruby​​ 1.8.7 文件.

Everything was working fine , until we decided to upgrade ruby to 1.8.7 from 1.8.6, and thats when all hell broke loose. When we compiled Ruby 1.8.7 from source it got installed into /usr/local/bin and Ruby 1.8.6 stayed in /usr/bin. Currently, we've uninstalled ruby 1.8.6 and by some stroke we deleted the ruby 1.8.7 files from /usr/local.

当我们尝试which ruby​​"时，它指向/usr/local.如果有人能帮助我们解决我们需要做的事情，让我们重回正轨，我们将不胜感激.也知道如何从/usr/local 卸载 ruby​​.我们尝试了 yum remove ruby​​ ，它从/usr/bin 中删除了 ruby​​.谢谢和干杯！

when we try "which ruby" it points to /usr/local. If anybody could help us out what we need to do get back on track , we would be very grateful.and also any idea how we can uninstall ruby from /usr/local. we tried yum remove ruby , which removed ruby from /usr/bin.Thanks and Cheers !

推荐答案

如果 1.8.6 位于 /usr/bin 中，则卸载它不是一个好主意.它归操作系统所有，预计会在那里.

It's not a good idea to uninstall 1.8.6 if it's in /usr/bin. That is owned by the OS and is expected to be there.

如果你把 /usr/local/bin 放在 /usr/bin 之前的 PATH 中，那么你已经安装在 /usr/local/bin 将在 /usr/bin 中的任何同名之前找到，有效地覆盖或更新它们，而实际上并不这样做.您仍然可以通过在 #! 中显式使用 /usr/bin 来访问它们.代码顶部的解释器调用行.

If you put /usr/local/bin in your PATH before /usr/bin then things you have installed in /usr/local/bin will be found before any with the same name in /usr/bin, effectively overwriting or updating them, without actually doing so. You can still reach them by explicitly using /usr/bin in your #! interpreter invocation line at the top of your code.

@Anurag 推荐使用 RVM，我将第二次推荐.除了操作系统的 1.8.6 之外，我还用它来管理 1.8.7 和 1.9.1.

@Anurag recommended using RVM, which I'll second. I use it to manage 1.8.7 and 1.9.1 in addition to the OS's 1.8.6.
