NodeJS,NPM和package.json依赖项

Question

读完npm-json(npm help json)之后,我package.json按如下方式构造了文件:{"name": "app name", "version": "0.1"}.该目录具有以下结构:

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

我熟悉的Node.js -做我需要重新安装在生产服务器上的所有模块部署的Node.js应用的时候,所以我试图通过执行安装的依赖关系npm install moduleDep --save,但我收到以下错误:

0 info it worked if it ends with ok
1 verbose cli [ 'node', '/usr/local/bin/npm', 'install', 'jquery', '--save' ]
2 info using npm@1.2.2

9 error cwd /home/roth/develop/build
10 error node -v v0.8.18
11 error npm -v 1.2.2

在我运行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？彻底的解释将是伟大的.

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,详情如下:

http://semver.org/

基本思想是使用三个数字代表major,minor和patch(major.minor.patch).
