use cross-env

cross-env cross-platform set up and use environment variables

In most cases, the windows platform is similar: NODE_ENV = production of command line instructions will be stuck, windows platform and POSIX using the command line there are many differences (eg POSIX, use $ ENV_VAR, in windows, use% ENV_VAR% ...)

cross-env makes that simple and different platforms use a unique command, without worrying about cross-platform issues

npm安装方式

npm i --save-dev cross-env

In npm script (mostly package.json) in such a configuration

{
  "scripts": {
    "build": "cross-env NODE_ENV=production webpack --config build/webpack.config.js"
  }
}

Run npm run build, so NODE_ENV they set up, without worrying about cross-platform issues
