Next.js tutorial, error running Next.js dev server (npm run dev)

Question

I'm doing the starter Next.js tutorial and encountering an error when I try to run the Next dev server and run my app.

Here is what my package.json file contains:

{
 "scripts": {
 "dev": "next dev"
 },
 "dependencies": {
 "next": "^12.2.0",
 "react": "^18.2.0",
 "react-dom": "^18.2.0"
 }
}

When running npm run dev, I get the following error:

> @ dev /Users/renaudj/Documents/Projects/next-app
> next dev
/Users/renaudj/Documents/Projects/next-app/node_modules/next/dist/trace/report/index.js:14
 reporters = [];

Anyone know what I'm missing here? Thank you!

• Phil: I'm guessing your Node version is less than 12.0. See Minimum Node.js version, you need at least 12.22.0
• Josh: Thanks, Phil. That was the issue.
• JK.: That means that this docs page is wrong because it says minimum node version is 10.13 - nextjs.org/learn/basics/create-nextjs-app/setup

Answer 3

Yes, updating your version of node will solve this issue.

Before doing this, delete the node_modules folder in your project.

Then to update node to the latest stable version, run the following command on your terminal:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

You may need to restart your terminal to see the version update which you check using:

node -v

Then reinstall your project using

npm install
