Vercel Next JS Dashboard Deployment Error Bcrypt

[jaymondmach]

Hi,

This is my first time learning Next JS and to get started I tried to learn with the Dashboard project from:
https://nextjs.org/learn. I’m currently on chapter 6 of this guide

After deploying my code to my Github Repo here: Github Repo. I’m not able to deploy to vercel because of this error:

I’ve tried converting my code to use bcryptjs instead but that didn’t work neither.

I’m not sure on how to fix this error thus I’ve reached out to this community for help.

Hi @jaymondmach, welcome to the Vercel Community!

Sorry that you’re facing this issue. Have you tried doing:
rm -rf node_modules/ to remove the node modules and doing pnpm i to reinstall the packages.

Also, which version of Node.js are you using? Can you check with node --version?

Hello,

I am using node version v22.12.0. To answer your question before yes I have already done rm -rf node_modules/

@jaymondmach @anshumanb I have exactly the same issue. The documentation needs a revision I think on this page App Router: Setting Up Your Database | Next.js OR the nextjs-dashboard source code itself needs an update. Who has made the nextjs-dashboard example? I am using Node v22.14.0 Here’s my error:

I fixed it by following the instructions of user kappy713 in Learn Next.js Chapter 6 setting up your database. Cannot find module bcrypt · vercel/next.js · Discussion #76822 · GitHub

@jaymondmach you probably did the wrong things to get from bcrypt to bcryptjs, follow the steps mentioned there and you will get it fixed! @anshumanb

Hi @behanprw, thanks for sharing the solution here. I’m posting it below for anyone stumbling here:

Run the following commands to remove bcrypt and add bcryptjs

pnpm remove bcrypt
pnpm add bcryptjs

Then update the /app/seed/route.ts file to use bcryptjs:

// /app/seed/route.ts
- import bcrypt from "bcrypt";
+ import bcrypt from "bcryptjs";
