如何从package.json为react设置NODE_ENV

{
  "name": "my-react-app",
  "version": "1.0.0",
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "dependencies": {
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "react-scripts": "4.0.3"
  }
}

{
  "name": "my-react-app",
  "version": "1.0.0",
  "scripts": {
    "start": "NODE_ENV=development react-scripts start",
    "build": "NODE_ENV=production react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "dependencies": {
    "react": "^17.0.2",
    "react-dom": "^17.0.2",
    "react-scripts": "4.0.3"
  }
}

if (process.env.NODE_ENV === 'development') {
  console.log('Running in development mode');
} else if (process.env.NODE_ENV === 'production') {
  console.log('Running in production mode');
}
