通过模板创建的项目： grunt-init grunt-init-command 跑过npm install -d .了，运行还是报错：（

D:\node\cmd>grunt
grunt-cli: The grunt command line interface. (v0.1.13)

Fatal error: Unable to find local grunt.

If you're seeing this message, either a Gruntfile wasn't found or grunt
hasn't been installed locally to your project. For more information about
installing and configuring grunt, please see the Getting Started guide:
