Подтвердить что ты не робот

ПРЕДУПРЕЖДЕНИЕ: Nokogiri был создан против LibXML версии 2.7.7, но динамически загружен 2.6.16

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)?

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

ОТВЕТЫ

Ответ 1

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.

Ответ 2

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

Ответ 3

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

Ответ 4

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.

Ответ 5

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.

Ответ 6

Пер Стелла Миранда, я последовал за шагами, чтобы решить мою собственную проблему нокогири на Mountain Lion:

  • gem удалить nokogiri
  • gem install nokogiri

Больше предупреждений nokogiri!

Ответ 7

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/...

Ответ 8

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.

Ответ 9

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.
