ошибка установки nokogiri gem

Я знаю, что есть много вопросов об этом драгоценном камне, но ни один ответ не работал для меня.

когда я бегу в SSH gem install nokogiri Я получаю эту ошибку:

Extracting libxml2-2.8.0.tar.gz into tmp/x86_64-unknown-linux-gnu/ports/libxml2/2.8.0... OK

Running patch with /home/user58952277/.gem/ruby/1.9.3/gems/nokogiri-1.6.2.1/ports/patches/libxml2/0001-Fix-parser-local-buffers-size-problems.patch...

*** 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.

мой хозяин сказал мне, что все библиотеки установлены.

************************************************************************

IMPORTANT!  Nokogiri builds and uses a packaged version of libxml2.



If this is a concern for you and you want to use the system library

instead, abort this installation process and reinstall nokogiri as

follows:



    gem install nokogiri -- --use-system-libraries



If you are using Bundler, tell it to use the option:



    bundle config build.nokogiri --use-system-libraries

    bundle install



However, note that nokogiri does not necessarily support all versions

of libxml2.



For example, libxml2-2.9.0 and higher are currently known to be broken

and thus unsupported by nokogiri, due to compatibility problems and

XPath optimization bugs.
