如何切换到旧版本的ruby/rails环境? [英] How do I switch to older versions of the ruby/rails environment?

问题描述

我正在尝试与Tekpub保持联系在rails screencast上构建您自己的博客.我还是非常红宝石的新手，问题在于我安装了Rails 3，而Rob使用的是旧版本(在我的脑海中:版本2.3.2).

I'm trying to keep along with the Tekpub Build your own blog on rails screencast. I'm still very much a ruby novice and the problem is that I have Rails 3 installed while Rob uses an older version (Of the top of my head: version 2.3.2).

我知道如何使用gem install rails --version=2.3.2获取该版本的rails，但是当我键入rails new时，该应用程序的版本为rails3.如何使该特定应用程序与旧版本一起使用?我知道这与rvm有关，但是除了基本的rvm use操作外，我不知道该怎么做.

I know how to get that version of rails with gem install rails --version=2.3.2 but when I type rails new the version of the application is rails 3. How do I make this particular app work with the older version? I know this has something to do with rvm but I have no idea how to do anything but the basic rvm use operation.

推荐答案

尝试

rvm use <ruby version>
rvm gemset create rails2.3.2
rvm <ruby version>@rails2.3.2
gem install rails --version=2.3.2

最后，在旧版本的rails中创建新的rails应用程序的语法仅为:

Finally the syntax to create a new rails app in older versions of rails was just:

rails <appanme>
