Why I can not run Npm run dev?

Question

Guys can you please help me on this I have trouble run npm run dev for my Laravel Mix. I followed links below but still error exist. Do i have a problem on my OS? I tried to remove node_modules, run npm install --global cross-env. and run NPM install again.

'cross-env' is not recognized as an internal or external command,

https://github.com/JeffreyWay/laravel-mix/issues/478

The error I always get when I ran npm run dev :

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! @ development: `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! Exit status 1
npm ERR! 
npm ERR! Failed at the @ development script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
