Установка Rails говорит, что библиотека "libxml2" отсутствует, хотя "brew install" говорит мне, что она есть
Я пытаюсь установить Rails на мою систему Mac Yosemite. Когда я изначально пробовал
sudo brew rails install
Я получил жалобы на отсутствие библиотеки "libxml2". Так что я установил, что с помощью
brew install libxml2
Но выполнение вышеуказанной команды для установки rails все равно не дает результатов, так как libxml2 не устанавливается. Что делать? Ниже приведен полный вывод из командной строки. Вы можете видеть, что когда я пытаюсь установить libxml2 снова, он говорит мне, что он уже установлен.

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:
gem install nokogiri -- --use-system-libraries
[--with-xml2-config=/path/to/xml2-config]
[--with-xslt-config=/path/to/xslt-config]
If you are using Bundler, tell it to use the option:
bundle config build.nokogiri --use-system-libraries
bundle install
Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.
