Express Req.body 在一台 PC 上为空，但在另一台 PC 上工作正常

Question

我在 1 台电脑上有一个 Firebase Express JS 项目文件夹。 当我运行 firebase serve 时，一切正常。

我正在尝试将我的工作 PC 更改为另一台。 我已经设置了我的 nodejs、firebase cli，并在这台新 PC 上打开了相同的文件夹（通过 OneDrive，所有文件都在本地可用）

但是，当我运行 firebase serve 并尝试 POST 时，我看到 req.body 是空的。

我错过了什么吗？

您应该运行npm install 以确保所有软件包都已正确安装。您的控制台中没有错误消息吗？
