'捆綁'的問題與紅寶石'遊戲盒'

Question

我正在與寶石'遊戲盒'第一次，我遇到了問題。我已經安裝了gem並生成了該指南指示的模板，但是當我試圖將其捆綁時，它將引發下面詳述的此錯誤。

    Install the library or try one of the following options to extconf.rb: 

     --with-xml2-config=/path/to/xml2-config 
     --with-xml2-dir=/path/to/libxml2 
     --with-xml2-lib=/path/to/libxml2/lib 
     --with-xml2-include=/path/to/libxml2/include 


extconf failed, exit code 1 

Gem files will remain installed in /home/user_id/company_office/lib/dependencies/ruby/2.1.0/gems/libxml-ruby-2.8.0 for inspection. 
Results logged to /home/user_id/company_office/lib/dependencies/ruby/2.1.0/extensions/x86_64-linux/2.1.0/libxml-ruby-2.8.0/gem_make.out 
An error occurred while installing libxml-ruby (2.8.0), and Bundler cannot 
continue. 
Make sure that `gem install libxml-ruby -v '2.8.0'` succeeds before bundling. 

我已經嘗試使用gem install libxml-ruby -v '2.8.0'以及sudo gem install libxml-ruby -v '2.8.0'其輸出以下：

$ gem install libxml-ruby -v '2.8.0' 
ERROR: While executing gem ... (Errno::EACCES) 
    Permission denied @ rb_sysopen - /var/lib/gems/2.1.0/gems/libxml-ruby-2.8.0/HISTORY 

我新望紅寶石和Linux所以道歉，如果這是一個愚蠢的問題。 謝謝

看起來像你缺少必需的C庫。在猜測中，我會說你需要安裝libxml2-dev（或者其他所謂的Linux包管理器）。
