Installazione di nokogiri Mac OS X 10.8.2 XCode installato

Question

Tentativo di installare nokogiri su Mountain Lion. Stavo usando Ruby 1.8.7 ma appena aggiornato alla versione 1.9.3, ma ha impedito l'installazione del bundle dal lavoro.

Per inciso, ho potuto ovviare a questo problema disinstallando Ruby 1.9.3 e tornando a 1.8.7. tuttavia questo è ovviamente una soluzione non ottimale dato che non voglio essere bloccato sul 1.8.7 per il resto del tempo ...

An error occurred while installing nokogiri (1.5.5), and Bundler cannot continue. 
Make sure that `gem install nokogiri -v '1.5.5'` succeeds before bundling. 

Ho scaricato XCODE compresi gli strumenti di sviluppo, quindi non so perché non verrà installato nokogiri ...

Quando provo ad installare nokogiri direttamente, ottengo:

Answer 1

Dopo breve ricerca scopro che cosa problema può essere risolto semplicemente creando link simbolico

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2 

lavori per me spero anche per te

gem install nokogiri 
Building native extensions. This could take a while... 
ERROR: Error installing nokogiri: 
    ERROR: Failed to build gem native extension. 

     /Users/morozovm/.rvm/rubies/ruby-1.9.3-p327/bin/ruby extconf.rb 
checking for libxml/parser.h... *** extconf.rb failed ***

Answer 2

penso che questo è il bit più importante del messaggio di errore:

warning: Insecure world writable dir /usr/local in PATH, mode 040777 

una parte del processo di creazione è piagnucolare che tale directory dispone di autorizzazioni tali che chiunque può scrivere su di esso. Potresti provare a scovarlo - o potresti aggiustarlo.

Answer 3

Prova questi. Ho affrontato lo stesso problema e ha funzionato per me. Prima installa libxml2 e poi esegui di nuovo bundler.

brew install libxml2 
brew link libxml2 

Fonte: http://decielo.com/articles/11/rails-3-on-lion-hey-ho-lets-go

Aggiornamento:

Spero che avete installato homebrew. Se non si dispone di homebrew, suggerirò di installare homebrew e quindi installare libxml2 e quindi bundler. Non utilizzare le porte Mac nel caso in cui non si abbia homebrew.

Aggiornamento:

Non è una questione di strumenti a linea di comando. Sta fallendo in libxml. Provate a leggere l'errore e si vedrà

checking for libxml/parser.h... *** extconf.rb failed *** 

E questo è il problema
