如何调试gem安装失败的原因？

标签： ruby rubygems gem

我正在尝试使用gem install geoutm安装geoutm。 Github存储库没有问题页面，所以我试图自己解决问题然后提交拉取请求。这就是问题所在：

$ 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

它说“已成功安装”，但试图要求宝石失败。详细安装不是更有用：

$ gem install geoutm --verbose

手动下载并在没有安装的情况下使用时，宝石可以完美运行。

问题是我不知道如何找出类型错误发生的位置。我找不到任何安装日志或更详细的输出标志。知道我怎么能弄清楚这个错误吗？

感谢Arup Rakshit的评论，我尝试了这个命令：

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

我得到了错误的回溯：

使用

的输出 
$ gem install --backtrace ...

你可以进一步做到

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

里面的byebyg类型：

(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

我正在努力寻找geoutm中的错误，但现在可以使用

进行安装 
$ gem install -N geoutm
