NPM Run Build The Syntax of command is incorrect

Using this tutorial: http://www.zsoltnagy.eu/step-by-step-environment-setup-of-the-react-developer-no-legacy-2016-standards/ I encountered a vague error after typing npm run build.

If you seen my previous question the package.json only has a slight variation and I suspect its something to do with these lines (the spaces in the file/directory names): "build": "webpack -d && copy src/app/index.html dist/index.html && webpack-dev-server --hot --inline --colors --progress --content-base src/", "build-prod": "webpack -p && copy src/app/index.html dist/index.html"

But I'm unsure how to resolve it.

Thank-you.
