我该如何调试gem安装失败的原因？ [英] How do I debug why a gem install fails?

问题描述

我尝试使用 gem install geoutm geoutm C $ C>。 Github存储库没有问题页面，所以我试图自己解决这个问题，然后提交一个请求。这是问题：



 $ gem install geoutm 
获取：geoutm-1.0.1.gem（100％）
成功安装geoutm-1.0.1 
错误：在执行gem时（TypeError）
没有将数组隐式转换为字符串

它说成功安装，但试图要求创业板失败。详细安装并没有多大用处：

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

错误：执行gem时... （TypeError）

当手动下载并在没有安装的情况下使用时，gem完美地工作。
$ b

问题是我不知道如何确定类型错误发生在哪里。我无法找到任何安装日志或更详细的输出标志。任何想法如何我可以找出这个错误？

解决方案

使用从输出

  $ 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 
  

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 
在/home/tallakt/.rvm/gems/ruby-2.0.0-p0/gems/rdoc-4.0.1/lib/rdoc/rubygems_hook.rb:171 $创建断点1 b $ b（byebug）c 
  

我正在寻找geoutm中的错误，但现在安装可以使用



  $ gem install -N geoutm 
  

跳过了RDoc生成

I'm trying to install geoutm using gem install geoutm. The Github repository doesn't have an issues page, so I'm trying to fix the issue myself then submit a pull request. This is the issue:

$ 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

It says "successfully installed", but trying to require the gem fails. Verbose install isn't much more useful:

$ 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

The gem works flawlessly when downloaded manually and used without installation.

The issue is that I don't know how to figure out where the type error occurs. I can't find any install logs or more verbose output flags. Any idea how I can figure out this error?

解决方案

Using the output from

$ gem install --backtrace ...

you can further do

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

Inside byebyg type:

(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

I am working on finding the bug in geoutm, but for now installation is possible using the

$ gem install -N geoutm

that skips RDoc generation
