node.js - 咕噜声 - 得到 "Local Npm module "xxx"not found. 它是安装 ?"What' s 造成的吗？

Question

我刚刚收到一份 grunt 包的副本，但我是 grunt 的新手，并且无法找到一些问题的答案。最大的问题是不知道下面的错误来自哪里 - 有人可以告诉我这是来自哪里吗？这两个文件都在同一个目录中。

$ grunt
>> Local Npm module "grunt-contrib-clean" not found. Is it installed?
>> Local Npm module "grunt-contrib-concat" not found. Is it installed?
>> Local Npm module "grunt-contrib-copy" not found. Is it installed?
>> Local Npm module "grunt-contrib-cssmin" not found. Is it installed?
>> Local Npm module "grunt-contrib-handlebars" not found. Is it installed?
>> Local Npm module "grunt-contrib-jshint" not found. Is it installed?
>> Local Npm module "grunt-contrib-qunit" not found. Is it installed?
>> Local Npm module "grunt-contrib-uglify" not found. Is it installed?
>> Local Npm module "grunt-preprocess" not found. Is it installed?
>> Local Npm module "grunt-wrap" not found. Is it installed?
>> Local Npm module "grunt-debug-task" not found. Is it installed?

您可能没有在本地安装必要的软件包。尝试 npm install (sudo npm install) 以确保你做到了。
