Solve - 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

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

shell
npm install -g node-gyp npm install bcrypt

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

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
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.

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
# 👇️ delete node_modules and package-lock.json rm -rf node_modules rm -f package-lock.json # 👇️ clean npm cache npm cache clean --force npm install npm install bcrypt@latest
Make sure to restart your IDE if the error still persists. VSCode often glitches and a reboot solves things sometimes.

If you're still getting the "Cannot find module 'bcrypt'" error, open your package.json file and make sure it contains the bcrypt package in the dependencies object.

package.json
{ // ... rest "dependencies": { "bcrypt": "^5.0.1", // ... rest } }

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

shell
npm install

Or install the latest version of the package by running:

shell
npm install bcrypt@latest
