我正在尝试使用. gem install geoutmGithub 存储库没有问题页面，所以我尝试自己解决问题，然后提交拉取请求。这是问题：

$ gem 安装geoutm
获取：geoutm-1.0.1.gem (100%)
成功安装geoutm-1.0.1
错误：执行 gem 时...（类型错误）
    没有将 Array 隐式转换为 String

它说“成功安装”，但尝试要求 gem 失败。详细安装并没有多大用处：

$ gem install geooutm --verbose

当手动下载并在不安装的情况下使用时，gem 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。知道如何找出这个错误吗？

使用来自的输出

$ gem install --backtrace ...

你可以进一步做

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

内部 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

我正在寻找geoutm中的错误，但现在可以使用

$ gem install -N geoutm

感谢 Arup Rakshit 的评论，我尝试了这个命令：

gem install geooutm --debug --backtrace --verbose

我得到了一个很好的错误回溯：
