Jak mogę debugować, dlaczego instalacja gemów nie powiedzie się?

Question

Próbuję zainstalować geoutm przy użyciu gem install geoutm. Repozytorium Github nie ma strony z problemami, więc próbuję rozwiązać problem, a następnie przesłać żądanie pobrania. To jest problem:

$ 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

Mówi "pomyślnie zainstalowany", ale próba zażądania gem nie powiedzie się. Dokładna instalacja nie jest zbyt użyteczna:

$ 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

Klejnot działa bezbłędnie, gdy jest pobierany ręcznie i używany bez instalacji.

Problem polega na tym, że nie wiem, jak ustalić, gdzie występuje błąd typu. Nie mogę znaleźć żadnych dzienników instalacji lub bardziej szczegółowych flag wyjściowych. Masz pomysł, jak wymyślić ten błąd?

Answer 1

Korzystanie wyjście z

$ gem install --backtrace ... 

ci może ponadto wykonać

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

wewnątrz byebyg typ:

(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 

pracuję nad znalezieniem błąd w geoutm, ale na razie instalacja jest możliwa przy użyciu

$ gem install -N geoutm 

że przeskakuje pokolenia rdoc

Answer 2

Dzięki komentarzu Arup Rakshit za Próbowałem tego polecenia:

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

I mam piękny ślad błędu:
