Я не могу понять, почему я получаю эту ошибку от Nokogiri, когда я запускаю Rails. Из того, что я знаю, кажется, что что-то еще вызывает загрузку более старой версии libxml2, которую затем заканчивает использовать Nokogiri, а не версию, с которой она была скомпилирована.
Что мне нужно сделать, чтобы заставить это работать без предупреждения (и с правильным libxml2)?
Im работает на Macbook с OS X 10.5.8:

WARNING: Nokogiri was built against LibXML version 2.7.7, but has dynamically loaded 2.6.16
HI. You're using libxml2 version 2.6.16 which is over 4 years old and has
plenty of bugs. We suggest that for maximum HTML/XML parsing pleasure, you
upgrade your version of libxml2 and re-install nokogiri. If you like using
libxml2 version 2.6.16, but don't like this warning, please define the constant
I_KNOW_I_AM_USING_AN_OLD_AND_BUGGY_VERSION_OF_LIBXML2 before requring nokogiri.

В конце концов, мне пришлось установить драгоценный камень против конкретных версий xml2 и xslt, которые я установил:
gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.7.7/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.7.7/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.26
Проблема была, скорее всего, плохим управлением библиотекой, переключением между менеджерами пакетов без достаточной осторожности.
Исправление для Nokogiri w. libxml2 2.7.8 loading libxml2 2.7.3
Хотелось добавить к приведенным выше ответам: Если у вас нет libxml2 в каталоге Cellar на OSX, вы можете установить его на это с помощью homebrew, как описано на домашней странице Nokogiri (homebrew 0.8 или выше, тест с brew -v):
brew install libxml2 libxslt
brew link libxml2 libxslt
gem install nokogiri -- --with-xml2-lib=/usr/local/Cellar/libxml2/2.7.8/lib --with-xml2-include=/usr/local/Cellar/libxml2/2.7.8/include
У меня было другое предупреждение:
WARNING: Nokogiri was built against LibXML version 2.7.7, but has dynamically loaded 2.7.8
восстановил камень с новой библиотекой, чтобы избавиться от предупреждения:
gem install --no-rdoc --no-ri nokogiri -- --with-xml2-include=/opt/local/include/libxml2 --with-xml2-lib=/opt/local/lib
Принятое решение не сработало для меня, но это:
gem install --no-rdoc --no-ri nokogiri -- --with-xml2-include=/usr/include/libxml2 --with-xml2-lib=/usr/lib
Это компилируется в системной библиотеке MacOS. Возможно, Macports (который я предпочитаю brew) неправильно настроен на моей машине.
Nokogiri был построен правильно, но сначала нужно было создать один камень и загрузить старую библиотеку libxml2.
В вашем приложении сначала нужно сначала указать nokogiri, чтобы приложение загрузило динамическую библиотеку libxml2 вместо старой версии libxml2, загруженной драгоценными камнями, которая не указала, какую библиотеку загружать.
Пер Стелла Миранда, я последовал за шагами, чтобы решить мою собственную проблему нокогири на Mountain Lion:
Больше предупреждений nokogiri!
Убедитесь, что это не просто проблема компиляции ruby. Это просто появилось на OSX Mountain Lion, так как системный libxml был набит, но ruby был скомпилирован на предыдущем libxml. Это можно решить, удалив и переустановив ruby.
Мой ответ на другой поток для справки: fooobar.com/questions/198478/...
У меня была такая проблема, вам действительно нужна две версии libxml в вашей системе? В противном случае удалите всю старую версию libxml и на всякий случай принудительно переустановите nokogiri.
У меня была такая же проблема. Все, что я сделал, это добавить строку в мой Gemfile, чтобы явно потребовать самую последнюю версию nokogiri (начиная с 3/17/2013, 1.5.6), затем я сделал bundle update nokogiri, и она исправила проблему.
