私はいつもNokogiri was built against LibXML version 2.9.3, but has dynamically loaded 2.9.2というエラーを受けていましたので、修正することにしました。Gem：nokogiri gemのためのRailsアプリケーションのloaderror
私はこのウェブサイトhttp://www.railsbling.com/posts/fix_nokogiri_warning/を見つけて指示に従いました。

************************************************************************
IMPORTANT NOTICE:
Building Nokogiri with a packaged version of libxml2-2.9.4.
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.

なぜノコギリが突然の問題を引き起こしているのかよく分かりません。
macOS Sierraにアップグレードするだけで変更しましたか？ libxmlを再インストールする必要があります。 –
