红宝石 – 不能安装Nokogiri宝石,“libxml / parser.h”没有找到

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.

我试着给安装人员提示如下：

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

...

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

...

但它仍然不安装：

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

我在Ubuntu 11.10.

输出：

“dpkg-query -l | grep xml”和“dpkg-query -l | grep xslt”

失败似乎在海湾合作委员会的一边：

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

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

%> gcc hello.c
