安装hpricot

Question

我正在尝试安装hpricot，并且出现以下错误。我确实安装了xcode，但我不确定我还缺少了什么。

$ 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. 

我也试过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

Answer 1

我不认为hpricot支持了。你应该看看nokogiri，它要快得多，而且记录完备。

编辑：我刚才检查的角度来说，Hpricot GitHub的页面（https://github.com/hpricot/hpricot/），他们也建议你使用引入nokogiri：

Hpricot has ended. Please consider an alternative like nokogiri.

编辑＃2：如果你正在运行在安装它时出错，很可能是因为您缺少libxml和其他库，您需要通过自制软件或macports进行安装。所有所需的库和安装说明可以在这里找到：

Answer 2

它看起来像你没有libxml的，或者libxml的开发库，从引入nokogiri生成的错误消息。

Answer 3

使用Kubuntu 14.04我首先安装了ruby-dev，然后安装了hpricot（错误“ERROR：Failed to build gem native extension。”）。
