gem install nokogiri -v '1.6.8.1' schlägt fehl

Question

Erstellen einer neuen Rails App und ein Problem mit Nokogiri bekommen. Gesagt, versuchen Sie gem install nokogiri -v '1.6.8.1', die mit der Ausgabe unten versagt. Ich habe versucht, Gemfile.lock zu löschen und Gemfile von einer anderen App zu verwenden, die kein Problem hat - bundle install schlägt immer noch fehl. Der ursprüngliche Fehler ist bundle install, der weiterhin in anderen Anwendungen funktioniert.

Von Konsole:

gem install nokogiri -v '1.6.8.1'

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.

Answer 1

Ich versuchte @ the_basterd Empfehlung. Das hat nicht funktioniert, aber die Referenz war gut - danke the_basterd. Was aus dieser Referenz gearbeitet wurde:

brew install libxml2

bundle config build.nokogiri --use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2

Referenz: https://github.com/sparklemotion/nokogiri/issues/1483

spätere Buchungen in diesem ref gesagt, was ich gepostet oben "ist stark von der Nokogiri empfohlen gegen"

brew unlink xz; bundle install; brew link xzist bevorzugt.

Answer 2

Führen Sie dieses zuerst:

xcode-select --install

Vom Terminal laufen:

sudo xcodebuild -license

Answer 4

Ich habe dieses Problem mit nokogiri-1.6.8.1 bei der Verwendung von bundle install --path vendor/bundle zur direkten Installation in ein Projekt in einem Google Drive-Synchronisierungsordner festgestellt. Der Hangup schien mit libxml2 verwandt zu sein.

Beim Lesen des GitHub-Problems, auf das von @Greg und @the_basterd verwiesen wird, habe ich festgestellt, dass someone was having trouble installing into a Box sync folder. Das Verschieben meines Projektordners an einen anderen Ort hat funktioniert.

Nicht sicher, was das zugrunde liegende Problem bei der Installation in einem Sync-Ordner ist, aber ich würde interessiert sein zu erfahren, ob jemand irgendwelche Gedanken hatte.

Haben Sie dies nicht mit Dropbox getestet, aber vielleicht würde das auch Probleme verursachen.
