mkdir [文件名 ] 创建项目文件

mkdir lodashDemo

 

cd [文件名] 进入项目文件

cd lodashDemo

 

nvm -v 查看nvm版本，确定nvm已安装

nvm -v Node Version Manager …

 

 

ls 查看项目文件目录，为空

nvm use 6使用第六版本的node.js

nvm use 6 Now using node v6.3.0 (npm v3.10.3)

 

 

npm init -y 在项目文件下创建package.json

npm init -y Wrote to /home/car/lodashDemo/package.json: { “name”: “lodashDemo”, “version”: “1.0.0”, “description”: “”, “main”: “index.js”, “scripts”: { “test”: “echo \”Error: no test specified\” && exit 1” }, “keywords”: [], “author”: “”, “license”: “ISC” }

 

 

ls 查看项目文件目录，新增了一个package.json文件

ls package.json

 

 

npm install –save lodash 下载lodash并修改package.json中的

npm install –save lodash lodashDemo@1.0.0 /home/car/lodashDemo └── lodash@4.14.0 npm WARN lodashDemo@1.0.0 No description npm WARN lodashDemo@1.0.0 No repository field.

 

 

package.json中的内容

{ “name”: “lodashDemo”, “version”: “1.0.0”, “description”: “”, “main”: “index.js”, “scripts”: { “test”: “echo \”Error: no test specified\” && exit 1” }, “keywords”: [], “author”: “”, “license”: “ISC”, “dependencies”: { “lodash”: “^4.14.0” } }

 

 

ls 查看项目文件目录，新增了一个node_modules文件夹，内含lodash文件

ls node_modules package.json

 

 

npm install

npm WARN lodashDemo@1.0.0 No description npm WARN lodashDemo@1.0.0 No repository field.

 

 

之后在js文件夹中调用时语句如下：

let _ = require("lodash");let demo = _.chunk(['a','b','c','d'],2);console.log(demo);
