试图让node express app运行

Question

我的计算机（mac）上安装了node，mongodb和redis，并尝试使用以下说明测试此应用https://github.com/vinkaga/node-backbone

Install and run MongoDB
Install and run Redis.io
Edit config.js if you are running MongoDB or Redis.io from another machine or non-default port
Start server by typing "node server.js"

之前从未使用过node或express并天真地假设运行node server.js足以让一切都开始，我做到了，但它说

![Error: Cannot find module 'express'][1]

这是应用程序的目录

这是package.json文件。为了让它在本地机器上运行，我还需要做些什么吗？

{
    "name":"YOUR-PROJECT-NAME",
    "description":"YOUR PROJECT DESCRIPTION",
    "author":"YOUR NAME <your@emailaddress.com>",
    "version":"0.0.1",
    "dependencies":{
        "connect":">=2.1.2",
        "express":"2.x.x",
        "connect-redis" : ">=1.3.0",
        "jade":">=0.24.0",
        "ejs" : ">=0.7.1",
        "mongoose":">=2.5.14",
        "socket.io":">=0.9.5",
        "connect-assetmanager":">=0.0.27",
        "connect-assetmanager-handlers" : ">=0.0.18"
    },
    "devDependencies":{
        "vows":">=0.6.2",
        "mocha":">=1.0.1",
        "should":">=0.6.1",
        "request":">=2.9.x",
        "soda":">=0.2.5"
    },
    "engine":"node >= 0.6.12"
}
