Come risolvere il "[BUG] errore di segmentazione"?

Question

Sto usando un Mac OS con Snow Leopard 10.6.8 e RVM 1.10.3, Ruby 1.9.3-p125, Ruby on Rails 3.2.2 e rspec-rails-2.8.1. Ho correttamente installato e configurato tutte le gemme, ma quando nella finestra di Terminale faccio funzionare l'ordine rake spec ottengo il seguente:

$ rake spec 
/<ABSOLUT_PATH>/.rvm/gems/ruby-1.9.3-p125/gems/yard-0.7.5/lib/yard/cli/command.rb:10: [BUG] Segmentation fault

Come posso risolvere il problema?

Nota: Ho notato che il problema si verifica a volte, a caso!

Nel mio Gemfile ho:

... 

group :development, :test do 
    gem "rspec-rails" 
    gem 'webrat' 
end 

group :test do 
    gem 'factory_girl_rails' 
    gem 'cucumber-rails' 
    gem 'turn', :require => false 
end 

... 

Answer 1

CURA: Sulla base delle informazioni che ci ha fornito fino ad ora, sembra aver trovato un bug in Ruby 1.9.3. Vi consiglio di segnalarlo al team principale di Ruby.

Fino a quando questo errore non viene risolto, è necessario trovare un modo per aggirarlo. Per trovare un modo per aggirarlo, è necessario ottenere maggiori dettagli su esattamente ciò che fa e non lo innesca.

Nella traccia stack che hai postato, sembra che la riga 68 di bundler/runtime.rb richieda la gemma del cantiere. Usando Ruby 1.9.3, prova a richiedere la gemma del cantiere, da IRB o da un semplice script di test. Questo fa scattare l'errore? In caso contrario, andare al metodo che "realer" chiama in "bundler" (bundler.rb, riga 118). Prova a chiamare quel metodo (qualunque esso sia) da uno script di test. Questo fa scattare l'errore? ...e così via.

Fortunatamente, quando si installano gemme di Ruby, il codice sorgente è disponibile nella directory "gems" e si può studiarlo e modificarlo. Ho anche dovuto "hackerare" il codice sorgente delle mie gemme prima di risolvere i problemi (fino a quando una versione fissa della gemma è stata rilasciata).

Answer 2

Ho lo stesso problema, arresti anomali casuali relativi a Yard quando si esegue rspec.

Ho trovato un altro post che ha risolto il problema per me. Rimossa la dipendenza da "pry-doc".
