Question

当试图安装宝石激光器时，我得到一个错误，激光需要激光！

我不是在寻求如何安装激光的帮助，而是如何调试出错的方法

以下是我尝试使用本地版本的vanilla安装时获得的内容

C:\Documents and Settings\a.grimm\Desktop\code\sandbox\laser>gem install pkg\laser-0.5.2.gem
Fetching: polyglot-0.3.1.gem (100%)

ERROR:  Error installing pkg\laser-0.5.2.gem:
        laser requires laser (>= 0)

再试一次：

C:\Documents and Settings\a.grimm\Desktop\code\sandbox\laser>gem install pkg\laser-0.5.2.gem
ERROR:  Error installing pkg\laser-0.5.2.gem:
        laser requires laser (>= 0)

我尝试使用gem help install

列出的开关

我尝试查看https://github.com/michaeledgar/laser/blob/master/laser.gemspec和https://github.com/michaeledgar/laser/blob/master/Rakefile，但找不到循环依赖。

我使用的解决方法是去Jedi并使用--force选项。现在我正在处理一个不同的安装错误！

根据bug report，这是由于珠宝商和捆绑商之间的冲突。这就解释了为什么我无法识别特定的违规行代码。

如何调试由于循环依赖而失败的rubygem安装？
