        ]
    },
}`

这是我的 package.json ，我使用 'STORYBOOK_THEME=red STORYBOOK_DATA_KEY=12345 npm run storybook' cmd，但是没有用。这是故事书官方website解释环境变量的使用。，我是否以错误的方式使用它？

Answer 1

这个问题已经解决了。我使用的是windows系统，我必须输入'set STORYBOOK_THEME=red'来设置环境变量，然后我可以通过'process.env.STORYBOOK_THEME'来获取这个变量。

我改变了脚本如下:

    "scripts": {
    "book": "set STORYBOOK_THEME=red&&start-storybook -p 9001 -c .storybook"
  }

有用!
