Fix Error: Cannot find module 'fs-extra'

If you see the error Cannot find module 'fs-extra', don't worry. This is a common Node.js issue. It happens when the module is missing or not installed correctly.

What causes this error?

The error occurs when Node.js cannot locate the fs-extra module. This usually happens for three reasons:

1. The module is not installed. 2. The installation failed. 3. The module path is incorrect.

How to fix the error

Here are the best solutions to resolve this issue quickly.

1. Install fs-extra

First, try installing the module. Open your terminal and run:

npm install fs-extra

If you need it as a development dependency, use:

npm install fs-extra --save-dev

2. Check node_modules

After installing, verify the module exists in node_modules. Look for the fs-extra folder.

If it's missing, delete node_modules and package-lock.json. Then run npm install again.

3. Verify package.json

Ensure fs-extra is listed in your package.json. It should appear in either dependencies or devDependencies.

{
  "dependencies": {
    "fs-extra": "^11.0.0"
  }
}

4. Global installation

If the error persists, try installing globally:

npm install -g fs-extra

5. Clear npm cache

A corrupted cache can cause installation issues. Clear it with:

npm cache clean --force

Common mistakes to avoid

1. Don't forget to run npm install after adding dependencies. 2. Check for typos in your require statement. 3. Ensure your Node.js version is compatible.

Example usage

Here's how to properly use fs-extra in your code:

const fs = require('fs-extra');

// Copy a file
fs.copySync('source.txt', 'destination.txt');

If successful, this will copy the file without errors.
