我正在尝试rake erd来为我的rails应用程序中的模型生成图。我在windows 7上并且安装了graphviz
当我奔跑
rake erd OR rake erd filetype=dot出现以下错误
$ rake erd --trace
** Invoke erd (first_time)

** Execute erd:options

Verify that Graphviz is installed and in your path, or use filetype=dot.

这可能是因为您的rails应用程序中没有模型。请转到您的app/model并确保存在模型文件。如果没有，请尝试生成模型并定义它们的关系。
