Ruby bundle install error with json-1.7.3
ruby-on-rails, rubygems
Solution
You are missing ruby-dev or ruby-1.9-dev package as described in this stackoverflow question. Install development package files first and then trying installing the gem.
Problem
I am getting following error while installing ruby gems. I am using Ubuntu ``` Installing json (1.7.3) with native extensions 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:1:in `<main>' Gem files will remain installed in /var/lib/gems/1.9.1/gems/json-1.7.3 for inspection.

Make sure that `gem install json -v '1.7.3'` succeeds before bundling. ``` I just saw this link, and not sure what to do with devkit*.exe files on ubuntu.
