无法安装Nokogiri gem,"libxml/parser.h"未找到,但它的存在,为什么？

Question

我试图安装Nokogiri但我总是得到一个编译错误:

checking for libxml/parser.h... *** extconf.rb failed ***

但是,我已经安装了它和所有其他依赖项.

我尝试给安装程序提示如下:

%> gem install nokogiri -- --with-xml2-lib=/usr/lib/ --with-xml2-include=/usr/include/libxml2/

...

checking for libxml/parser.h... *** extconf.rb failed ***

...

但它仍然没有安装:

%> find /usr/include/ -name "parser.h"    
/usr/include/libxml2/libxml/parser.h
...

我在Ubuntu 11.10上.

失败似乎是海湾合作委员会的一方:

%> cat hello.c
#include <stdio.h>

main()
{
   printf("Hello World \n");
}

%> gcc hello.c

这会奏效.
