Installation Problem On Debian Wheezy (using RVM): nokogiri and multi_json

[gm9...@gmail.com]

Hi,
I tried to install community_engine following the README.

I installed RVM on a Wheezy, then RVM and 1.9.3:
tom@webby:~/ce$ ruby -v
ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-linux]

gem install rails
# -> rails (3.2.13)

I set up a new rails project:
rails new coengine
....
cd coengine
and added this line to Gemfile:
gem 'community_engine', :git => 'git://github.com/bborn/communityengine', :branch => 'rails3
(a little bit different than README says, there seems to be a problem too)

I added application_config.rb and then I tried to start step 3 from README:

tom@webby:~/coengine$ bundle install --binstubs

      multi_json (~> 1.0.0) ruby

    uglifier (>= 1.0.3) ruby depends on
      multi_json (1.7.7)

This problem I tried to solve via update:

tom@webby:~/coengine$ bundle update

      nokogiri (~> 1.5.0) ruby

    community_engine (>= 0) ruby depends on
      nokogiri (1.6.0)

And now I don't have any idea what to do......

Perhaps anyone out there who could give me a hint?
Thanks in advance

Hi,

I had suffered from this problem lately and after a long walkthrough on the internet i came up with the solution for this nightmare.

First of all in your Gemfile add the following:

gem 'community_engine'

gem 'multi_json'

gem 'nokogiri', '~> 1.5.0'

Then delete the Gemfile.lock file in your application

Finally run the bundle install command. 

I hope this helps a lot.
