Hello guys, I'm starting to learn Nodejs two weeks ago. And I have cloned a small project of my teacher on Github to my local computer.
It's a mall project about Nodejs, that helps pull data from an API and display data to the browser. Like this:
index.js file
const fetch = require('node-fetch');
var express = require('express');
var app = express();
app.get('/', async (req, res) => {
const result = await getUser();
console.log(result);
});
var server = app.listen(5000, function () {
console.log('Server is running..');
});
async function getUser() {
try {
const response = await fetch('https://randomuser.me/api/');
if (!response.ok) {
throw new Error(`Error! status: ${response.status}`);
}
const result = await response.json();
return result;
} catch (err) {
console.log(err);
}
}
After building the source code, I ran node index.js command I see an issue : Error: Cannot find module 'node-fetch'.
Error: Cannot find module 'node-fetch'

I think you pull from Github, this project is already installed
node-fetchpackage. You can openpackage.jsonfile and check it. If right, you can run the command below:npm updateIt will auto-update all packages for you.
If not, you can install
node-fetchpackage by using the command:npm install node-fetchHope this answer will useful for you.

To install node-fetch, you can run the command:
npm install node-fetchSometimes you need to clear and install npm first by using the command:
npm install -g npm npm cache clean npm updateIt worked for me.
