Railsアプリケーションでモデルの図を生成するためにerdをレーキしようとしています。私はWindows7を使用していて、graphvizがインストールされています
私が走るとき
rake erd OR rake erd filetype=dot
次のエラーが発生します
$ rake erd --trace
** Invoke erd (first_time)
** Invoke erd:generate (first_time)

** Execute erd:options

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