[761] process.env.NODE_ENV getting set to development no matter what.

echo $NODE_ENV gives me production

Package.json on OSX:

"scripts": {
  "dev": "backpack dev",
  "build": "NODE_ENV=production nuxt build && backpack build",
  "start": "node build/main.js",
  "generate": "nuxt generate",
  "lint": "eslint --ext .js,.vue --ignore-path .gitignore .",
  "precommit": "npm run lint"
}

npm run build runs with process.env.NODE_ENV set to development. npm run start runs with process.env.NODE_ENV set to development and rebuilds every time.

I have verified both of the above with console.log statements.

I am using Nuxt with Express.

I do not understand where my environment is getting set to development. I have nothing in my nuxt.config.js that sets this environment variable.

Any help would be appreciated.
