I''m not a ruby guy, trying to install the knife-ec2 plugin for Chef, following the steps here

All is fine until I do 

$ bundle install --path vendor

which produces the error below:

Make sure that `gem install nokogiri -v '1.6.1'` succeeds before bundling.

Please let me know if posting additional files or console output would help.

  • I took the liberty of embedding the text you linked to. When practical, SO favors having everything needed be in the question itself. It's more convenient for the reader; also, links can go bad. – Wayne Conrad Feb 12 '14 at 13:39
  • THanks Wayne Conrad. I actually tried to do it with the 4 space indent, but it wasn't working out for me because of the other, deeper indents. Mind sharing how you did that? – 3z33etm Feb 12 '14 at 14:29
  • nm. pasted into notepad ++, hit tab once, cnp again, fixed. thx – 3z33etm Feb 12 '14 at 14:39

You need to install libxml. The stacktrace shows you're on Ubuntu, so:

sudo apt-get install libxml2

See the Nokogiri readme for more information.

  • will give this a try. I thought the purpose of using a gemfile and bundle was to avoid dependency issues? – 3z33etm Feb 12 '14 at 01:46
  • libxml2 installs without any issues, but nokogiri still gives the exact same error. http://pastebin.com/AHv98wKk – 3z33etm Feb 12 '14 at 02:00
  • Did you install libxslt as well? http://stackoverflow.com/questions/20890808/install-nokogiri-1-6-1-under-ruby-2-0-0p353-rvm-based-installation-fails-osx – sethvargo Feb 12 '14 at 02:56
  • Yessir. sudo apt-get install libxml2-dev libxslt-dev ruby1.9.1 ruby1.9.1-dev (individually not at once) all completed with no issues. still getting a nokogiri install error. (Can't paste inline due to comment length limit) http://pastebin.com/CyfcKswM – 3z33etm Feb 12 '14 at 14:47
  • Are you using the omnibus Ruby? That Ruby is just for Chef. You need to install your own Ruby. – sethvargo Feb 12 '14 at 15:48
  • I used curl -L https://www.opscode.com/chef/install.sh | sudo bash to install Chef, I think that's the omnibus installer. So I need to install a sep ruby in order to get chef plugins to work? I'll try that. Edit: doesn't apt-get install ruby1.9.1 in my previous post address this? – 3z33etm Feb 12 '14 at 15:57
