我正在尝试在 nodered 中为我的树莓派 pi3 安装传感器 Node 。该传感器为空气质量传感器SDS011，安装命令如下:
npm install node-red-contrib-sds011
好吧，我认为这是一些更新的问题，实际上是命令
node -v
给我“v4.4.5”作为答案。
问题是，当我尝试使用一些 npm 命令(如上面的传感器命令)时，我总是会收到此错误作为答案:

此外，如果我尝试启动 node.red 控制台，则会出现类似的错误:

一些建议？
非常感谢。
最佳答案
NodeJS v4.4.5 非常旧，完全不再支持(已于 2018 年 4 月停产)。
Node-RED 目前至少需要 NodeJS 版本 8.x ( https://nodered.org/docs/faq/node-versions )
您需要升级您的系统，我建议您使用 here 链接到的脚本因为它将升级到最新的 NodeJS 和 Node-RED。
