Cannot find module 'lodash' error [Solved]

# Cannot find module 'lodash' error [Solved]

To solve the error "Cannot find module 'lodash'", make sure to install the lodash package by opening your terminal in your project's root directory and running the following command: npm i lodash.

If you use TypeScript, install the typings by running npm i -D @types/lodash.

shell

Copied!
Error Cannot find module 'lodash'
[ERR_MODULE_NOT_FOUND]: Cannot find package 'lodash'

Open your terminal in your project's root directory (where your package.json file is located) and run the following command.

shell

Copied!
npm install lodash

# 👇️ only if you use TypeScript
npm install --save-dev @types/lodash

npm install lodash

This will add the lodash package to the dependencies of your project.

Now you should be able to import and use the package.

index.js

Copied!
import _ from 'lodash';

console.log(_.add(100, 200)); // 👉️ 300

import and use lodash module

If you use TypeScript and get the "Cannot find module 'lodash' or its corresponding type declarations" error, open your tsconfig.json file and make sure the types array contains the string node.

tsconfig.json

Copied!
{
  "compilerOptions": {
    "types": [
      "node"
    ]
  },
}

This should fix the error and now TypeScript should be able to find the type definitions for the lodash module.

# Delete your node_modules and reinstall your dependencies

If the error is not resolved, try to delete your node_modules and package-lock.json (not package.json) files, re-run npm install and restart your IDE.

If you are on macOS or Linux, issue the following commands in bash or zsh.

shell

Copied!
#  for macOS and Linux
rm -rf node_modules
rm -f package-lock.json
rm -f yarn.lock

# 👇️ clean npm cache
npm cache clean --force

# 👇️ install packages
npm install

If you are on Windows, issue the following commands in CMD.

cmd

Copied!
# for Windows
rd /s /q "node_modules"
del package-lock.json
del -f yarn.lock

# 👇️ clean npm cache
npm cache clean --force

# 👇️ install packages
npm install

Make sure to restart your IDE and dev server if the error persists. VSCode often glitches and needs a reboot.

# Verify `lodash` is in your `dependencies` object

If the "Cannot find module 'lodash'" error persists, open your package.json file and make sure it contains the lodash package in the dependencies object.

package.json

Copied!
{
  // ... rest
  "dependencies": {
    "lodash": "^4.17.21",
  },
  "devDependencies": {
    // 👇️ only if you use TypeScript
    "@types/lodash": "^4.14.180",
  }
}

You can try to manually add the line and re-run npm install.

shell

Copied!
npm install

Or install the latest version of the package:

shell

Copied!
npm install lodash@latest

# 👇️ only if you use TypeScript
npm install --save-dev @types/lodash@latest

install latest version of lodash module
