未找到本地npm模块“grunt-prettify”。它是否安装？

Question

我安装了Node Js，然后安装了Grunt。当我运行Grunt Copy命令时，cmd显示这些错误：

local npm module "grunt-prettify" not found. is it installed? 

local npm module "grunt-autoprifixer" not found. is it installed? 

local npm module "grunt-contrib-cssmin" not found. is it installed? 

local npm module "grunt-contrib-uglify" not found. is it installed? 

任何人都可以告诉我如何摆脱这些消息。提前致谢！
