Cannot find module 'bcrypt' error in Node.js [Solved]

# Cannot find module 'bcrypt' error in Node.js

To solve the error "Cannot find module 'bcrypt'", install the node-gyp and bcrypt packages. The bcrypt module uses node-gyp for its build and installation.

After the installation, restart your IDE and your development server.

cannot find module bcrypt

shell

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

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

shell

Copied!
npm install -g node-gyp

npm install bcrypt

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

install bcrypt module

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

If the global installation of node-gyp fails, you might have to run the command prefixed with sudo.

shell

Copied!
# 👇️ If you got permissions error, run with sudo
sudo npm install -g node-gyp

npm install bcrypt

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

If the error persists, restart your IDE and development server.

If the error is not resolved, open your terminal in your project's root directory and run the following commands:

shell

Copied!
npm install -g bcrypt

npm link bcrypt

The npm link command creates a symbolic link from the globally installed package to the node_modules/ directory of the current folder.

# 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.

shell

Copied!
# 👇️  (macOS/Linux) delete node_modules and package-lock.json
rm -rf node_modules
rm -f package-lock.json
rm -f yarn.lock

# 👇️  (Windows) delete node_modules and package-lock.json
rd /s /q "node_modules"
del package-lock.json
del -f yarn.lock

# 👇️ clean your npm cache
npm cache clean --force

# 👇️ install packages
npm install

npm install bcrypt@latest

Make sure to restart your IDE if the error persists. VSCode often glitches and a reboot solves things sometimes.

# Verify the `bcrypt` module is in your `dependencies` object

If you still get the error, open your package.json file and make sure it contains the bcrypt package in the dependencies object.

package.json

Copied!
{
  // ... rest
  "dependencies": {
    "bcrypt": "^5.0.1",
    // ... rest
  }
}

npm install

run npm install command

Or install the latest version of the package by running:

shell

Copied!
npm install bcrypt@latest

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

install latest bcrypt version
