npm安装安装未在package.json中指定的额外软件包
我在AWS ec2实例上有一个相当典型的package.json 。 我正在运行npm install ，而不是安装
{ "name": "angular-app-server", "description": "Back end server to support our angular app", "version": "0.0.1", "private": true, "dependencies": { "assert": "^1.3.0", "async": "^0.9.0", "bcrypt-nodejs": "0.0.3", "body-parser": "^1.13.1", "connect-multiparty": "^1.2.5", "express": "~3.0", "express-namespace": "~0.1.1", "express-session": "^1.11.1", "forever": "^0.14.2", "mongodb": "^2.0.36", "multiparty": "^4.1.2", "nodemailer": "^1.3.4", "open": "0.0.3", "passport": "~0.1.12", "passport-local": "~0.1.6", "request": "~2.16.6", "svgo": "^0.5.3" }, "devDependencies": { "grunt": "~0.4", "grunt-contrib-jshint": "~0.2.0", "grunt-contrib-nodeunit": "~0.1.2", "rewire": "^2.0.1", "supervisor": "~0.4.1" } }
它安装了数十个包（通过cd node_modules ＆ ls ）：

这可能是什么原因？
感谢您的任何build议或帮助。
这是NPM 2和NPM 3之间的区别。NPM 3将把依赖关系的第一个版本作为对等体，并将其他版本的依赖关系嵌套在一起。
我猜它看起来更丑，但占用更less的空间。
他们是你想要的模块的依赖关系。 这是无法避免的。
