解決：Bundler停在gem json安裝

Question

我試圖用bundler安裝susy2/sass/compass。 我的Gemfile：

source "https://rubygems.org" 
gem 'sass', '~> 3.3.2' 
gem 'susy', '~> 2.1.1' 
gem 'json', '~> 1.8.1' 
gem 'compass', '~> 1.0.0.alpha.19' 

捆綁安裝顯示錯誤

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. 

     /usr/bin/ruby1.9.1 extconf.rb

    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 /home/bernie/.bundler/tmp/6210/gems/json-1.8.1 for inspection. 
Results logged to /home/bernie/.bundler/tmp/6210/gems/json-1.8.1/ext/json/ext/generator/gem_make.out 
An error occurred while installing json (1.8.1), and Bundler cannot continue. 
Make sure that `gem install json -v '1.8.1'` succeeds before bundling.
