sh: 1: webpack: not found

Question

I am developing React+Django application When I call npm run dev

I receive an error

sh: 1: webpack: not found

package.json

  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "dev": "webpack --mode development ./src/index.js --output ./static/frontend/main.js",

  },
  "description": ""
}

Found out that in ./node_modules/.bin/ i have only loose-envify -> ../loose-envify/cli.js* I read this question Webpack command not found, but didn't understand how to fix my error.

You're trying to use webpack but it's not listed under devDependencies.

In your terminal, run npm install --save-dev webpack and then try again.

I may not be 100% correct with that command since I usually use yarn and the command is yarn add --dev webpack - but I am 100% sure that this is your issue.
