Hit an "Error: Cannot Find Module" in Node.js? It means a module can’t be located. Let’s fix it fast in this 2025 guide!

What Causes "Error: Cannot Find Module"?

This error occurs in Node.js when a module import fails. Common causes:

• Wrong Path: Incorrect file or directory path.
• Missing Dependency: Module not installed via npm.
• Typo: Misspelled module name or file.

Test this locally (create main.js and run node main.js):

// main.js
const missingModule = require('./nonexistent');
console.log(missingModule);

This will throw "Error: Cannot Find Module './nonexistent'."

How to Fix It: 3 Solutions

Let’s resolve this error with practical steps:

(Diagram: Developer imports module, gets error, checks path/installs, imports successfully.)

Solution 1: Check File Path

Ensure the module path is correct:

// Wrong
const myModule = require('./wrong/path/to/module');

// Fixed
const myModule = require('./correct/path/to/module');
console.log(myModule);

Use relative or absolute paths and verify files exist.

Solution 2: Install Missing Modules

Install dependencies with npm:

// Wrong
const lodash = require('lodash'); // Not installed

// Fixed
// Run: npm install lodash
const lodash = require('lodash');
console.log(lodash);

Run npm install to add missing packages.

Solution 3: Fix Typos

Check for spelling mistakes in module names:

// Wrong
const fs = require('fss'); // Typo

// Fixed
const fs = require('fs');
console.log(fs);

Double-check module names and file extensions.

Quick Checklist

• Is the path correct? (Check file/directory)
• Is the module installed? (Run npm install)
• Any typos? (Verify names)
