1. install required packages via apt-get:

apt-get install ruby rubygems ruby1.8-dev build-essentials libxml2-dev libxslt1-dev

(though i’m pretty sure i had build-essentials already installed.)

2. update ruby gems with:

gem install rubygems-update
gem update --system

3. unhork /usr/bin/gem using the process defined @ http://nickdenardis.com/2008/11/29/fixing-uninitialized-constant-gemgemrunner-nameerror-ubuntu/ by modifying the top of /usr/bin/gem to look like:

require 'rubygems'
require 'rubygems/gem_runner'
#Gem.manage_gems

4. set the path

export PATH=$PATH:/var/lib/gems/1.8/bin

5. install the sproutcore gem:

gem install sproutcore

and get ready to type ‘Y’ a lot, except for when you have to type a number.

after this, the hello world example worked well for me.

gem install rubygems-update
update_rubygems

ERROR: Error installing sproutcore:
merb-core requires RubyGems version >= 1.3.0

I get this error…

ERROR: Error installing sproutcore:
merb-core requires RubyGems version >= 1.3.0


Any ideas?

I’m running Ubuntu Ibex, natively on an Asus Eee pc 1000.

I’ve already run through all of the other installations…

I re-ran the “apt-get install ruby1.8-dev” step (not sure if this was necessary) then waited a while for the deferred processing to complete (not sure if that was necessary either

Then I ran “gem install sproutcore” a second time and this time everything worked perfectly.

Thank you very much for your post! I tried using SproutCore under Windows but was unsuccessful so I was very happy to find the information you provided here.

You could try:

gem cleanup
gem update

any better?

Thanks very much for your post. I’m having some trouble getting this to work. I got a VMWare appliance with Ubuntu pre-installed. I then tried to follow the steps you suggested.

It looked like everything worked until I got to this step:

gem install sproutcore

at this point, I got this error message:
Bulk updating Gem source index for: http://gems.rubyforge.org
ERROR: While executing gem … (Gem::GemNotFoundException)
Could not find sproutcore (>0) in any repository

Can you suggest what I might be doing wrong?

Thanks,

Notre

Thanks for the suggestion; that makes sense.

Tim

I’d suggest moving your additions to /etc/profile to /etc/profile.d/sproutcore.sh and chmod +x the script.

This way, you can have application specific configs and not touch /etc/profile, which may get updated in the course of normal system updates and blow away your modifications.
