Laravel Mix cross-env error

Following along with the Laravel Mix and the Front-end video, I'm receiving the following error when running npm run dev

npm ERR! Failed at the @ development script 'cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js'.

npm ERR! Make sure you have the latest version of node.js and npm installed.
npm ERR! If you do, this is most likely a problem with the  package,
npm ERR! not with npm itself.

Tell the author that this fails on your system:
npm ERR!     cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

I have the latest NPM npm install --save latest-version and verified webpack and cross-env are installed

npm install webpack
npm install cross-env

Any ideas how to fix?
