NodeJS,NPM和package.json依赖项

标签: node.js npm production-environment production

在阅读npm-json(npm help json)之后,我构建了package.json文件,如下所示:{"name": "app name", "version": "0.1"}。该目录具有以下结构:

/
|-- 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,因此我尝试通过执行npm install moduleDep --save来安装依赖项,但是我收到以下错误:

0 info it worked if it ends with ok

在运行main模块之前,我必须使用NPM来安装依赖项。 是否有任何我可以执行的命令将安装然后将依赖项添加到package.json?彻底的解释会很棒。

Node.js使用3部分版本控制系统,如“0.0.1”或“1.2.3” - 你的“0.1”不起作用。这称为语义版本控制,详情请参见:

http://semver.org/

基本思想是你使用三个代表major,minor和patch(major.minor.patch)的数字。
