如何調試由於循環依賴而失敗的rubygem安裝？

試圖安裝寶石激光器時，出現激光需要激光的錯誤！如何調試由於循環依賴而失敗的rubygem安裝？

我沒有那麼多尋求幫助如何安裝激光，但如何調試出了什麼問題

以下是我所得到的，當我嘗試香草安裝的本地版本

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)

再次嘗試：

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)

我試圖使用由gem help install

列出的交換機

我試過看https://github.com/michaeledgar/laser/blob/master/laser.gemspec和https://github.com/michaeledgar/laser/blob/master/Rakefile，但找不到循環依賴。

我使用的解決方法是去Jedi並使用--force選項。現在我正在處理不同的安裝錯誤！

你有沒有試過與包維護者交談？我不是寶石專家，但這聽起來好像是他包裝中的一個錯誤。 – Andy
