无法通过公共 IP 地址访问 create-react-app

Question

我试图通过访问 [IP_ADDRESS]:3001 从另一台计算机打开我的 create-react-app，但我的 react 应用程序只能在 localhost:3001 上连接。我已尝试执行以下命令但出现错误：

C:\Users\HP\OneDrive\mealplanner\client>HOST=0.0.0.0 npm run start
'HOST' is not recognized as an internal or external command, operable program or batch file.

所以我将变量添加到我的 npm 启动脚本中：

"scripts": {
    "start": "set PORT=3001 && set HOST=0.0.0.0 && react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
}

这不会给我一个错误，但是，我在命令提示符下收到此警告：

Attempting to bind to HOST environment variable: 0.0.0.0 
If this was unintentional, check that you haven't mistakenly set it in your shell.

然后，在访问 localhost:3001 或 [IP_ADDRESS]:3001 时，我从 chrome 收到此错误：
