安装模块 node-red-node-arduino 失败：

Question

我正在尝试通过 node-red 网站说明中概述的管理调色板安装功能安装 node-red node-arduino。 Node-red 安装在我的 Windows 10 PC 上，我通过 USB COM 端口连接了一个 Arduino。 Arduino 已将标准固件加载到板上。当我尝试安装 arduino-node 时，我收到一条冗长的错误消息，似乎没有成功搜索 Python，尽管 node-arduino 的要求中没有提到 Python。这是错误消息：

prebuild-install WARN install No prebuilt binaries found (target=14.16.1 runtime=node arch=x64 libc= platform=win32)

注意：以上是错误消息，不是代码，但必须将其标记为这样才能被接受

我是 Node-Red 的新手，非常感谢任何帮助。

Python 是必须构建本机组件的任何 nodejs 包的要求。在这种情况下，它需要构建node-serial 模块才能访问COM 端口。您需要安装受支持的 Python 版本才能使其正常工作。
