Question

I'm making react small application with webpack.
Running scripts in package.json but is not working.
Building developing mode success.
Building production mode with no option failed.

Scripts

// 
scripts {
  "build-prod": "webpack -p --mode production",
  "build-dev": "webpack -d --mode development"
}

Error message is

npm run build-prod

I'm using these version

"webpack": "^4.29.6",
"webpack-cli": "^3.3.0",

So the command will be

"prod": "webpack -p --mode=production",
"start": "webpack --mode=development",
