Problemi nell'installazione di nokogiri con RVM 1.9.3 su Centos 6.2

/usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/mkmf.rb:381:in `try_do': 
The compiler failed to generate an executable file. (RuntimeError) 
You have to install development tools first.

Ho installato Ruby 1.9.3 utilizzando RVM sul mio server CentOS 6.2. Quando provo a eseguire gem install nokogiri, produce l'output di seguito. Ho già visitato il sito nokogiri e installato le dipendenze libxml2 e libxslt usando yum:Problemi nell'installazione di nokogiri con RVM 1.9.3 su Centos 6.2

sudo yum install -y gcc ruby-devel libxml2 libxml2-devel libxslt libxslt-devel

Inoltre ho installato i pacchetti libxml2 e libxslt utilizzando rvm pkg install e reinstallato rubino dopo.

Ho cercato una soluzione, ma non ho ancora trovato nulla. Tutte le idee sarebbe apprezzato :)

Building native extensions. This could take a while...

Potete incollare il contenuto di mkmg.log – Hashken

è necessario fornire il contenuto del file mkmf.log in modo per chiunque di dare consigli. –

Ho fissato questo, in qualche modo. Ho rimosso tutti i pacchetti RVM (libxml2, iconv, libxslt, etc.) ad eccezione di zlib utilizzando rvm pkg uninstall <package> Allora ho reinstallato 1.9.3 utilizzando rvm reinstall 1.9.3

Poi ho fatto un gem install nokogiri e ha funzionato bene ...

Non capisco completamente perché funzioni ora, forse i pacchetti rvm libxml2, iconv, libxslt sono nocivi?

Ho apportato alcune modifiche al mio ambiente relative a tali librerie e dovuto al fatto che la mia installazione di Ruby è stata interrotta. Dopo averlo reinstallato, nokogiri è stato installato correttamente, grazie. –

c'è un modo per disinstallare tutti i pacchetti rvm escludendo zlib in una volta?grazie – Ravin

Il problema principale sembra essere che i file binari di rvm/brew/port/any compilati per Lion avranno alcune dipendenze di librerie obsolete/rimosse, causando sia problemi di compilazione che di runtime per software di livello superiore. Ho risolto questo problema sul mio sistema mettendo a fuoco tutti i miei pacchetti brew e port-managed, ricompilando/reinstallando tutte le mie dipendenze, ricompilando il ruby gestito da RVM 1.9.3-p194, e infine "gem install nokogiri" funzionava senza problemi.

Ho sprecato un sacco di tempo cercando di convincere i miei pacchetti compilati obsoleti a funzionare. Invece, basta reinstallare il suddetto (assicurandosi che in realtà stai ricompilando/collegando) e dovresti stare bene.

Intendi reinstallare ruby 1.9.3-p194? Ho provato a farlo attraverso rvm ma non ha risolto il problema? Questo potrebbe essere dovuto alla sua non ricompilazione/linking e, in caso affermativo, come faccio ad assicurarmi che sia ricompilato/linkato? – Ravin

Devi anche disinstallare qualsiasi pacchetto di dipendenze che potresti aver installato con RVM (libxml2, libiconv, ecc.) –

La ragione è che gem install nokogiri chiamare path/to/your/gems/ruby-1.9.3-p194/gems/nokogiri-1.5.5/ext/nokogiri/extconf.rb, e in extconf.rb di file,

LIB_DIRS = [ # Prima di ricerca/opt/local per macports '/ opt/local/lib',

# Then search /usr/local for people that installed from source 
'/usr/local/lib', 

# Check the ruby install locations 
LIBDIR, 

# Finally fall back to /usr 
'/usr/lib',

ma il vostro lib libxml2 non può in precedenza paths.so è necessario assicurarsi extconf.rb possono trovare libxml2 lib La mia soluzione: Il mio centos è a 64 bit, libxml2 è installato in/usr/lib64, e copio usr/lib64/libxml2.so a /usr/lib/libxml2.so per risolvere il problema.
