[!] There was an error parsing Gemfile: [!] There was an error parsing Gemfile: You cannot specify the same gem twice with different version requirements. You specified: nokogiri (>= 1.6.7.2) and nokogiri (>= 0). Bundler cannot continue.

from /home/redmine/redmine/plugins/redmine_backlogs/Gemfile:11

-------------------------------------------

gem "icalendar"

gem "nokogiri"

gem "open-uri-cached"

. Bundler cannot continue.

Dir.glob File.expand_path("../plugins/*/{Gemfile,PluginGemfile}", FILE) do |file|

end

I install all dependences with gem, but not execute bundler.

nokogiri is defined in Redmine's Gemfile with version and in backlog's Gemfile without version. If you comment out the nokogiri dependency in backlog's Gemfile, the bundle command will execute successfully.

You may face with a similar problem with capybara gem, but in that case, you need to comment out it from Redmine's Gemfile, because backlog's one's defining it with a more specific version.
