Rails Tutorial: nokogiri-1.5.2 error on bundle install
nokogiri, railstutorial.org, ruby-on-rails, rubygems
Solution
You need the header files for compiling extension modules for Ruby.
You can get the proper version for your version of ruby with:
`sudo aptitude install ruby-dev`
Problem
After working through the RVM setup, rspec and guard sections of chapter 3 of the Ruby on Rails Tutorial, whenever I run `bundle install` I get the following error dump: ``` Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /usr/bin/ruby1.9.1 extconf.rb /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError) from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from extconf.rb:5:in `<main>' Gem files will remain installed in /home/dan/.bundler/tmp/17577/gems/nokogiri-1.5.2 for inspection. Results logged to /home/dan/.bundler/tmp/17577/gems/nokogiri-1.5.2/ext/nokogiri/gem_make.out An error occured while installing nokogiri (1.5.2), and Bundler cannot continue. Make sure that `gem install nokogiri -v '1.5.2'` succeeds before bundling. ``` In the gem_make.out: ``` Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /usr/bin/ruby1.9.1 extconf.rb /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file --mkmf (LoadError) from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require' from extconf.rb:5:in `<main>' ``` I've been debugging for a while now and I think I'm stuck. Help would be GREATLY appreciated!
