************************************************************************ IMPORTANT NOTICE: 

Building Nokogiri with a packaged version of libxml2-2.9.4 with the following patches applied: 
    - 0001-Fix-comparison-with-root-node-in-xmlXPathCmpNodes.patch 
    - 0002-Fix-XPointer-paths-beginning-with-range-to.patch 
    - 0003-Disallow-namespace-nodes-in-XPointer-ranges.patch 

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 fühle mich wie ich alles versucht habe - bitte helfen!

Answer 1

ich alles neu installieren endete. Es kam von einem Problem mit make. Gelöst hier: https://github.com/rvm/rvm/issues/3995

Answer 2

Versuchen Installation nokogiri manuell

brew install libxml2 libxslt 

gem install nokogiri -v '1.7.1' -- --use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2 

Answer 3

Haben Sie, wenn Command Line Tools, um zu sehen geprüft installiert sind? Oft wird Nokogiri nicht installiert, wenn es keinen c-Compiler gibt.

Typ: $ xcode-select -p

Wenn Sie sehen: /Applications/Xcode.app/Contents/Developer Das vollständige Xcode-Paket ist bereits installiert.

Typ gcc Sie sollten eine Warnung sehen:

Alternativ können Sie einen Befehl verwenden, um Xcode Kommandozeilen-Tools zu installieren. Es wird eine ähnliche Alarmbox erzeugen. Hinweis: der doppelten Bindestrich:

$ xcode-select --install
