How to solve the npm ERR! Missing script: build

Learn, how to solve the npm ERR! missing script: “build” error in your JavaScript projects.

This error occurs due to one of the following reasons:

1. Using the build script without defining it inside the scripts object in your package.json file.

2. Running the npm run build command in a different directory.

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

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

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

Here is an example:

"scripts": {
     "build": "webpack --config webpack.config.js"
},

Here, I added a config file webpack.config.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 build script to the package.json file.

"scripts": {
     "build": "webpack --config webpack.config.js"
},
