Laravel 5.4 ‘cross-env’ Is Not Recognized as an Internal or External Command

Question

I\'m trying to run npm run dev for Laravel Mix and I get this error:

> @ dev D:\\projects\\ptcs
> cross-env NODE_ENV=development webpack -         


        

Answer 1

The following worked for Laravel 7.x (and should probably work for any other version as well given the nature of the issue).

npm uninstall --save-dev cross-env
npm install -g cross-env

Just moving cross-env from being a local devDependency to a globally available package.
