How to fix the npm ERR! Missing script: dev

Learn, how to fix the npm ERR! Missing script: “dev” error in your JavaScript projects.

This error occurs due to the following reasons:

1. Using the npm run dev command without defining it inside the scripts object in your

package.json file.

2. Running the “npm run dev” command in a different directory.

3. Not initialized a package.json file in your project directory.

Run npm dev
npm ERR! Missing script: "dev"
npm ERR!
npm ERR! To see a list of scripts, run:
npm ERR!   npm run

To fix the npm ERR! Missing script:“dev” error, add the dev script to your package.json file and open the root project directory in your terminal before running the npm run dev command.

Here is an example:

"scripts": {
     "dev": "node app.js"
},

Here, I added a dev file app.js, in your case it will be some other file.

If you don’t have package.json file in your project directory, you can initialize it by running the npm init -y command.

npm init -y

Now, add the dev script to the package.json file.
