收到节点模块文件夹后，安装npm软件包

Question

My name is Jaffer Syed and I am wondering how to install npm packages into my code. I am trying to install num2fraction https://www.npmjs.com/package/num2fraction but in you npm package video you didnt go into how to install npm packages and how to actually make it work in the javascript. I added the command for the package in the command line but it doesn't seem to work for some reason and when I find the error it keeps saying that the require is not defined.

my js looks like this for trying to implement the num2fraction

    var n2f = require('num2fraction')

     console.log(n2f(2.555)) 

thank you

Answer 1

here is a sample script for how I did what you're trying:

mkdir foo
cd foo
npm init

just accept all the default options here

npm install -s num2fraction

put your exact contents above into a file called foo.js in this directory and save

node foo.js

should output 511/200
