NodeJS，NPM和package.json依赖关系

读完npm-json（npm help json）后，我构建了如下文件package.json：{"name": "app name", "version": "0.1"}。该目录的结构如下：NodeJS，NPM和package.json依赖关系

/ 
|-- main.js 
|-- package.json

我熟悉Node.js - do I need to reinstall all the modules on the production server when deploying the Node.js app，所以我试图通过执行npm install moduleDep --save安装的依赖关系，但我收到以下错误：

0 info it worked if it ends with ok

之前，我可以运行main模块，我必须使用NPM来安装依赖关系。是否有任何可以执行的命令将安装，然后将依赖添加到package.json？彻底的解释会很好。
