installing hpricot

Question

我正在尝试安装hpricot，但收到以下错误。我确实安装了xcode，但我不确定我还缺少什么。

$ 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.

我也试过野卷。

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

Answer 1

我认为不再支持hpricot了。你应该看看nokogiri，它要快得多，而且有非常好的记录。

编辑：我刚刚查看了hpricot github页面(https://github.com/hpricot/hpricot/)他们还建议你使用nokogiri：

Hpricot已经结束。请考虑另一种选择，比如野村。

edit#2：如果你在安装它时遇到错误，很可能是因为你缺少libxml和其他库，你需要通过自制软件或macports安装这些库。所有必需的库和安装说明都可以在这里找到：

Answer 2

使用Kubuntu 14.04，我只需先安装ruby dev就可以安装hpricot（在错误"error:Failed to build gem native extension."之后）。
