Need to update RubyStack to Rails 2.2.2

Hi, I’m running Rails 2.1.1 installed from bitnami-rubystack-1.2-1-linux-installer on a Linux pc 2.6.24-etchnhalf.1-486 #1 Mon Jul 21 10:36:16 UTC 2008 i686 GNU/Linux machine.
I tried to update as described in Railscasts #137 but had no success.

Can someone help please.
Kind regards
Eugen

Hi euwero,

to install new version of Rails you can do the following: start rubyconsole, update rubygems and, install new rails version with correct shebang (adding -E option). That is:

$ <rubystack_path>/rubyconsole
$ gem update --system
$ gem install rails -v2.2.2 -E

After that, you should have correct version available:

$ rails -v 
Rails 2.2.2

To make your Rails applications work with the new version you should modify “<application_path>/config/environment.rb” with:

RAILS_GEM_VERSION = '2.2.2' unless defined? RAILS_GEM_VERSION

I hope it helps you

Hi carlos,
thanks for your help. These steps went OK, but Rails 2.2.2 needs gem 1.3 as described in http://railscasts.com/ #137.

$ <rubystack_path>/rubyconsole
$ gem update—system
$ gem install rubygems-update
$ update_rubygems

The last command doesn’t end.

Kind regards
Eugen

Hi,

it’s true I thought update—system was doing the upgrade.

To use update_rubygems, you can try commenting out the lines:

#RUBYOPT=rubygems
#export RUBYOPT

Once it has finished you should modify shebang in “<rubystack_path>/ruby/bin/gem” to be:

#!/usr/bin/env <rubystack_path>/ruby/bin/ruby

After that, you should get correct gem version

$ gem -v
1.3.1

Hi carlos,
thank you so much. This was a good help. I only had to modify the first line in
“<rubystack_path>/ruby/bin/update_rubygems” to
”#!/usr/bin/env <rubystack_path>/ruby/bin/ruby” before running it.
I think all is OK now.

Kind regards
Eugen

Will RubyStack 1.4 Final come with Rails 2.2 or not
By the time 1.4 final is released, Probably Rails 2.3 will also be released

We don’t know when RubyStack 1.4 Final will come out yet

Hi!

I have exact the same problem with RubyStack for Windows.
I tried to modify the “<rubystack_path>/scripts/setenv.bat” …
But it doesn’t work under Windows. ;)

Is there any way to update the Gems / Rails under Windows?

Okay I found a solution.
The Problem is that I’m using the Aptana-Studio in combination with RubyStack.

If somebody under Windows has the same problem:
Start Aptana Studio -> go to the console window -> type in: gem install rubygems-update

After that you have to open up a cmd prompt!!!
Run there the:

update_rubygems

command…

Test it unter Aptana – Console:
gem -v
1.3.1

Ok… Then:
gem update rails

Finish…

Regards

Great,

Thanks for posting the solution, this post could help other users who use RubyStack and Aptana.

Cheers
