Hello, i am running OSX 10.5 leopard with installed rails 2.2.2 at /  
usr/bin/. Having wanted to try rails 2.3, i created a gems directory  
at $HOME/gems and used ‘export GEM\_HOME=$HOME/gems’. Then i gave a  
'gem install rails --source [http://gems.rubyonrails.org](http://gems.rubyonrails.org) and installed  
rails 2.3 at $GEM\_HOME. I have also installed rake. However, when i  
run ‘rails’, the rails2.2.2 is executed. Can anyone help me with this  
minor problem ? Is there a way to run rails 2.3 instead of 2.2.2 ? i  
would not like to uninstall rails 2.2.2.

thanks in advance

You don’t need to uninstall rails – here’s my system output from

`sudo gem list --local rails`

\*\*\* LOCAL GEMS \*\*\*

rails (2.2.2, 2.1.0, 2.0.2, 1.2.6, 1.2.3)

If I want/need to use other than the latest version, I just put that  
into  
config/environment.rb e.g.

RAILS\_GEM\_VERSION = ‘2.1.0’ unless defined? RAILS\_GEM\_VERSION

Works just fine (and I’m also on Mac OS 10.5).

## HTH!

I might do something like this just to play w/ a 2.3 rails app:

$ cd play  
$ git clone git://github.com/rails/rails.git  
Initialized empty Git repository in /Users/cdemyanovich/play/rails/.git/  
…  
Resolving deltas: 100% (73189/73189), done.  
$ ruby rails/railties/bin/rails dummy  
create  
create app/controllers  
…  
create log/test.log  
$ cd dummy/vendor  
$ cp -R ~/play/rails/ rails  
$

In other words,

1. go to my play directory
2. clone rails
3. use the cloned rails to make a dummy app in my play directory
4. go to dummy/vendor
5. copy rails to dummy/vendor/rails (vendoring rails instead of relying  
on  
2.3 early release gems)
6. play w/ the app

By the way, if you’d prefer something other than sqlite3 as a db, do  
this in  
step 3

$ ruby rails/railties/bin/rails dummy -d mysql

see rails --help for more options
