javascript – 有没有办法从.js文件自动安装node.js依赖项？

var program = require('commander');
var cheerio = require('cheerio');

在 package.json文件中列出您的依赖项.然后,您可以运行npm install来安装所有依赖项.

这是package.json文件的示例.请注意如何定义依赖项：

{
  "name": "best-practices","description": "A package using versioning best-practices","author": "Charlie Robbins <charlie@nodejitsu.com>","dependencies": {
    "colors": "0.x.x","express": "2.3.x","optimist": "0.2.x"
  },"devDependencies": {
    "vows": "0.5.x"
  },"ENGIne": "node >= 0.4.1"
}
