24 error Make sure you have the latest version of node.js and npm installed.
24 error If you do, this is most likely a problem with the  package,
24 error not with npm itself.
24 error Tell the author that this fails on your system:
24 error     cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js
24 error You can get information on how to open an issue for this project with:
24 error     npm bugs
24 error Or if that isn't available, you can get their info via:
24 error     npm owner ls
24 error There is likely additional logging output above.
25 verbose exit [ 1, true ]

Previously it worked flawlessly. This are my node and npm versions:

node -v v6.10.1

npm -v 3.10.10

Any ideas?
