I'm trying Next for the first time (with npx create-next-app), but I'm not getting the scripts to work. npm run dev works fine, but next dev outputs zsh: mand not found: next. Why is this?

I'm on macOS 12.5, M1. Node version 16.13.1.

It works when I use the debug tool in VS Code.

package.json:

{
  "name": "blog-next",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start",
    "lint": "next lint"
  },
  "dependencies": {
    "next": "12.2.5",
    "react": "18.2.0",
    "react-dom": "18.2.0"
  },
  "devDependencies": {
    "eslint": "8.22.0",
    "eslint-config-next": "12.2.5"
  }
}

• Do you need to install the Next cli? nextjs/docs/api-reference/cli – MikeeeG Commented Aug 17, 2022 at 9:08
• 4 Directly typing next dev into a mand prompt means the OS has to recognize the next mand. This will only work if next itself is installed properly, independent of whatever project you have. Till then, npx next dev should work – user5734311 Commented Aug 17, 2022 at 9:12

You need to install the package globaly(system wide) npm -g install next

In my case, this was caused by running over an outdated Node version (v.14x).

After upgrading Node everything worked as expected (Dec 2023: v.20x).

Make sense in fact that Nextjs releases requires/patible with a range of NodeJs versions.

Please, update your NodeJs version.

# nvm users (node version manager)
nvm use 20

# node users
npm install -g node
npm install -g npm
