如何在Ubuntu 9.04上同时安装Rails 2.3.2和2.3.4？ [英] How to install Rails 2.3.2 and 2.3.4 simultaneously on Ubuntu 9.04?

问题描述

我需要在我的Ubuntu 9.04服务器上同时安装Rails 2.3.2和Rails 2.3.4。

当我运行时：

  sudo gem install rails 
  

...它安装了2.3.4版本。有没有一个单一的命令，我可以用来安装2.3.2与默认（最新）版本并行？

谢谢！

  sudo gem install rails -v = 2.3.2 
  

您必须为2.3.4单独安装

I need to install Rails 2.3.2 and Rails 2.3.4 simultaneously on my Ubuntu 9.04 server. How do I do this?

When I run:

sudo gem install rails

...it installs version 2.3.4. Is there a single command I can use to also install 2.3.2 parallel to the default (latest) version?

Thanks!

解决方案

use the -v option to gem:

sudo gem install rails -v=2.3.2

you'll have to do a separate install for 2.3.4 though
