I'm trying to install backlogs 0.9.9 plugin for redmine 2.1.2 under ubuntu 12.10.

Following the Backlogs installation guide

remine_install_path$ RAILS_ENV=production bundle exec rake db:migrate

rake aborted!
No such file to load -- nokogiri

However nokogiri seems to be there

$ gem list | grep nokogiri
nokogiri (1.5.5)

Am I doing something wrong ?

You need to edit the Gemfile and add the below line

gem "nokogiri"

to solve the dependencies

That fixed my problem, Thanks. I added gem "nokogiri", ">= 1.4.2" and reran bundle install --path vendor/bundle --without test development. Now I have the same error with prawn I imagine I should do the same. Shouldn't there be some commands to set the required dependencies ? – Pierre de LESPINAY Nov 20 '12 at 8:26
Actually yes, backlogs should contain the dependencies. I stupidly removed the Gemfile after having conflicting versions. I have put it back by re checking out backlogs – Pierre de LESPINAY Nov 20 '12 at 9:25
So putting it back resolved the error with prawn? – devav2 Nov 20 '12 at 9:28
Yes, all other errors (apart a conflicting version requirement for test-unit) I just commented out one of them – Pierre de LESPINAY Nov 20 '12 at 9:51
