安装hpricot

Question

我正在尝试安装hpricot，但得到了以下错误。我确实安装了xcode，但我不确定还遗漏了什么。

$ 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已经被支持了。你应该研究一下nokogiri，它的速度要快得多，而且有非常好的文档。

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已结束。请考虑一下像nokogiri这样的替代品。

edit#2:如果您在安装它时遇到错误，很可能是因为您缺少libxml和其他需要通过自制软件或macport安装的库。所有必需的库和安装说明都可以在以下位置找到：

Answer 2

根据nokogiri构建中的错误消息，您似乎没有libxml或libxml开发库。

Answer 3

使用Kubuntu 14.04我安装了hpricot (在出现错误" error : Failed to build gem native extension“之后。)只需先安装ruby-dev即可。
