安裝hpricot

Question

我正在嘗試安裝hpricot，並且出現以下錯誤。我確實安裝了xcode，但我不確定我還缺少了什麼。

$ gem install hpricot 
Building native extensions. This could take a while... 
ERROR: Error installing hpricot: 
    ERROR: Failed to build gem native extension. 

     /Users/user_name/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb 
checking for stdio.h... *** extconf.rb failed *** 
Could not create Makefile due to some reason, probably lack of 
necessary libraries and/or headers. Check the mkmf.log file for more 
details. You may need configuration options. 

我也試過nokogiri。

$ gem install nokogiri 
Building native extensions. This could take a while... 
ERROR: Error installing nokogiri: 
    ERROR: Failed to build gem native extension. 

     /Users/user_name/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb 
checking for libxml/parser.h... *** extconf.rb failed *** 
Could not create Makefile due to some reason, probably lack of 
necessary libraries and/or headers. Check the mkmf.log file for more

Answer 1

我不認爲hpricot支持了。你應該看看nokogiri，它要快得多，而且記錄完備。

編輯：我剛纔檢查的角度來說，Hpricot GitHub的頁面（https://github.com/hpricot/hpricot/），他們也建議你使用引入nokogiri：

Hpricot has ended. Please consider an alternative like nokogiri.

編輯＃2：如果你正在運行在安裝它時出錯，很可能是因爲您缺少libxml和其他庫，您需要通過自制軟件或macports進行安裝。所有所需的庫和安裝說明可以在這裏找到：

Answer 2

它看起來像你沒有libxml的，或者libxml的開發庫，從引入nokogiri生成的錯誤消息。

Answer 3

使用Kubuntu 14.04我首先安裝了ruby-dev，然後安裝了hpricot（錯誤「ERROR：Failed to build gem native extension。」）。
