Package.json - 无法安装模块

Question

我有一个空文件夹,我在其中创建了一个package.json文件,其中包含:

{
    "name":"sample project",
    "version":"0.0.1",
    "title":"My grunt App",
    "homepage":"http://gruntjs.com"
}

稍后在同一个文件夹中,我试图运行此命令:

npm install grunt --save-dev

但我得到这样的错误:根本无法安装grunt

D:\grunt2>npm install grunt --save-dev

无法理解这个问题.有人帮帮我吗？其实我正在尝试重现本教程:http://www.anujgakhar.com/2013/02/28/writing-a-simple-grunt-task-using-gruntjs/

不要在项目名称中使用空格.改变,例如,改为sample-project.(这是非常错误的第一线,顺便说一句:Error: Invalid name: "sample project")
