TypeError: Object.entries(...).flatMap 不是函数

Question

我创建了一个 React 应用程序，然后将 Tailwind 集成到它。当我跑时npm start，我收到了这个错误。

我今天遇到了同样的问题，并通过将 Node.js 更新到最新版本来解决它。

flatMap是在 Node.js v11 中引入的。您可能使用的是旧版本。您可以通过运行一下：node -v。

我建议使用NVM管理节点版本：

使用 cURL 安装非常简单：

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.0/install.sh | bash

然后重启你的终端，安装最新的 Node.js 版本只需运行nvm install node.

要检查您使用的 Node.js 版本是否已更改，您可以node -v再次运行。
