************************************************************************ 
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.

Ich habe versucht zu deinstallieren und installieren Sie es wieder, aber ich habe das gleiche Info

Wie kann ich es beheben?

Answer 1

Es könnte helfen:

brew uninstall xz

gem install nokogiri -v 1.6.8 oder gem install rails (Befehl Sie ausführen)
