How to fix npm ERR! code ENOSCRIPT npm ERR! No script found in npm

Run npm run without any arguments to see all available scripts:

npm run

This shows the complete list of scripts defined in your package.json, helping you find the correct name.

Make sure you're in the project root where package.json is located:

ls package.json

If the file doesn't exist, navigate to the correct directory:

cd /path/to/your/project

Open package.json and look for the scripts section:

{
  "scripts": {
    "start": "node index.js",
    "dev": "vite",
    "build": "vite build",
    "test": "jest"
  }
}

If your desired script is missing, add it with the appropriate command.

Common typos include:
- npm run bulid instead of npm run build
- npm run dve instead of npm run dev
- Extra spaces in the command

Script names are case-sensitive, so npm run Dev won't find a script named dev.

If the script genuinely doesn't exist, add it to package.json:

{
  "scripts": {
    "dev": "next dev",
    "start": "next start",
    "build": "next build"
  }
}

The command depends on your framework (Vite, Next.js, Create React App, etc.).

If there's no package.json at all, create one:

npm init -y

Then add your scripts manually or install your framework, which will set up appropriate scripts.
