失敗：RuntimeError：保存圖失敗！當運行耙erd命令

我想耙erd生成模型在我的rails應用程序的圖。我對Windows 7和graphviz的安裝失敗：RuntimeError：保存圖失敗！當運行耙erd命令

當我運行

rake erd OR rake erd filetype=dot

我收到以下錯誤

$ rake erd --trace

我怎麼可以編輯的寶石？ – amjad 2013-03-13 13:55:25

路徑在這裏：c：/Ruby193/lib/ruby/gems/1.9.1/gems/rails-erd-1.1.0/lib/rails_erd/diagram/graphviz.rb，只需編輯該文件 – leifg 2013-03-13 14:04:31

我現在正在更換Gem文件後發生錯誤$ rake erd rake中止！未初始化的常量RailsERD :: Domain :: Attribute :: Inspectable – amjad 2013-03-13 14:17:42

我在OS 10.9.2上遇到了同樣的問題。

解決方案

brew install graphviz

創建ERD - on Rails的工作4

erd --inheritance --direct --attributes=foreign_keys,content --filetype=dot 
dot -Tjpg erd.dot > erd.jpg

你也可以用PDF
