I think there's a problem on WIndows with NODE_ENV

Steps To Reproduce:

npm run dev

[JeffreyWay]

Can you do npm install cross-env and update your npm script?

[pderiy]

Yes it works with global cross-env, but without is a problem on windows.

[heavensloop]

It still doesn't work with global cross-env installed.

[mcanvar]

It works after adding cross-env before each NODE_ENV on the scripts.
