I am trying to build Noosfero (http://noosfero.org/), a project done in Ruby, but I am pretty new in Ruby and Linux (my current environment).
I am following the instructions in their tutorial (http://gitorious.org/noosfero/noosfero/blobs/master/INSTALL and http://gitorious.org/noosfero/noosfero/blobs/master/HACKING).
I was supposed to run an apt-get install with many packages, everything worked except for libgettext-ruby-data, to which I get a message that “E: Package libgettext-ruby-data has no installation candidate”.
I then download the source and try to run “rake db:schema:load”, which I get the following error:
“rake aborted!
uninitialized constant Dependencies
/home/user/noosfero/Rakefile:10”
My rake file is the following:
require(File.join(File.dirname(FILE), ‘config’, ‘boot’))
require ‘rake’
require ‘rake/testtask’
require ‘rake/rdoctask’
require ‘tasks/rails’ #this is the line that the dependency can’t be found
I searched around and found this question here: Uninitialized constant ActiveSupport::Dependencies::Mutex (NameError) , but changing the config files didn’t help and I could wasn’t able to downgrade my RubyGems because I do not know how to do that (gem -update returns a message that I have to do that using apt-get, but I can’t find out in which package the gem program is).
The first time I run Rake, I get a message saying:
“I: Installing Debian-installed Rails from /usr/share/rails into vendor/rails.
I: Please note that the recommended Rails version is 2.1.0, and that other versions might not work”
But I don’t know how to downgrade my Rails version.
I’ve got many paths to follow, so I’ve got many questions, I hope you can help me:
1- Does anyone knows how to fix it directly?
2- How can I downgrade Gems?
3- How can I downgrade Rails?
4- Where can I download gems and how can I install it? (The documentation provides a link, but this link is VERY strange: http://www.yotabanana.com/hiki/ruby-gettext.html?ruby-gettext ).
Any help is very appreciated.
Thanks,
Oscar
Edit: can this error be a problem in the project I downloaded and not in my environment? After some research I am starting to think it is, can it be?
This was a version conflict I had with the project I was trying to build, not it is solved 🙂
