npm Grunt loads, but then grunt command unrecognized

Question

I have used grunt on this computer before for other projects (4 months ago), and recently wanted to use grunt for a new project. I loaded grunt globally and then locally, but after that typing in $ grunt -v says grunt is not recognized as if it is not loaded, or perhaps the path is wrong? anyone got any ideas?

Update: 5/16/2016, I tried the below suggestion and loaded casper-cli globally and locally, and the grunt command still fails. Additionally, I tried another command 'casperjs' and that one is also failing even though that has worked perfectly for the last year or so. It appears all of my commands are not working anymore, what could possibly cause that?

您必须全局安装grunt-cli才能在控制台中使用grunt： npm install grunt-cli -g
