With time passing by, the dependencies listed in the Gemfile, are developed further, and require more recent version of Ruby, and the instructions for Linux Mint 17 LTS / Ubuntu 14.04 LTS need to be either updated, or the relevant dependencies version-locked conditionally if install is done on that system.
Currently
rake -> requires Ruby version >= 2.0.0.
You can do sudo apt-get install git ruby2.0 ruby2.0-dev bundler build-essential
And replace #!/usr/bin/env ruby with #!/usr/bin/env ruby2.0 in /usr/bin/bundle
Or change the symlink /usr/bin/ruby to point to ruby2.0 instead of ruby1.9.1
NOTE: the ruby version is in fact 1.9.3 but the name of the binary in Ubuntu don't reflect this
But after fixing the dependency rake:
nokogiri requires Ruby version >= 2.1.0.
But no ruby2.1 is available for Ubuntu 14.04 on the simple way
The last version that would work is nokogiri 1.6.8.1 which requires Ruby >= 1.9.2
If you specify the version above for nokogiri in Gemfile like this: gem 'nokogiri', '1.6.8.1' the install succeeds
I did a quick research, and at the time of the last know commit on Jan 4, 2015, the versions of the "problem gems" were rake: 10.4.2 and nokogiri: 1.6.5 and the ruby version required to succeed was 1.9.2.
