Come si esegue il debug del motivo per cui l'installazione di una gemma fallisce?

Question

Sto tentando di installare geoutm utilizzando gem install geoutm. Il repository Github non ha una pagina dei problemi, quindi sto provando a risolvere il problema e quindi inviare una richiesta di pull. Questo è il problema:

$ gem install geoutm 
Fetching: geoutm-1.0.1.gem (100%) 
Successfully installed geoutm-1.0.1 
ERROR: While executing gem ... (TypeError) 
    no implicit conversion of Array into String

Dice "installato correttamente", ma sta tentando di richiedere l'errore della gemma. Verbose installazione non è molto più utile:

$ gem install geoutm --verbose 
HEAD https://rubygems.org/latest_specs.4.8.gz 
302 Moved Temporarily 
HEAD https://s3.amazonaws.com/production.s3.rubygems.org/latest_specs.4.8.gz

La gemma funziona perfettamente quando scaricato manualmente e utilizzato senza installazione.

Il problema è che non so come capire dove si verifica l'errore di tipo. Non riesco a trovare alcun registro di installazione o più flag di output dettagliati. Qualche idea su come posso capire questo errore?

Answer 1

Utilizzando l'uscita dal

$ gem install --backtrace ... 

voi può inoltre fare

$ byebug /home/tallakt/.rvm/rubies/ruby-2.0.0-p0/bin/gem install geoutm-1.0.1.gem 

All'interno byebyg Tipo:

(byebug) break /home/tallakt/.rvm/gems/ruby-2.0.0-p0/gems/rdoc-4.0.1/lib/rdoc/rubygems_hook.rb:171 
Created breakpoint 1 at /home/tallakt/.rvm/gems/ruby-2.0.0-p0/gems/rdoc-4.0.1/lib/rdoc/rubygems_hook.rb:171 
(byebug) c 

Sto lavorando sulla ricerca del bug in geoutm, ma per ora l'installazione è possibile utilizzando il

$ gem install -N geoutm 

che salta generazione RDoc

Answer 2

Grazie al commento di Arup Rakshit ho provato questo comando:

gem install geoutm --debug --backtrace --verbose

E ho avuto un bel backtrace dell'errore:
