节点红色:“错误:<节点名称>"节点未部署"在树莓派 B+ 上 [英] Node-Red: &quot;Error: &lt;nodename&gt; node not deployed&quot; on Raspberry Pi B+

问题描述

上周我了解了 node-red(很有潜力！)，在 Raspberry Pi B+ 上安装它并按照基本教程进行操作后，我遇到了一些问题.

Last week I got to know node-red (what a potential!), and after installing it on a Raspberry Pi B+ and following the basic tutorials, I'm experiencing some issues.

当我按照 Inject + Debug 节点示例进行连接并部署它们时，我收到消息Deploy sucessfull".到现在为止还挺好.我在 http://localhost:1880 上本地运行它.

When I follow the Inject + Debug node example, wire them, and deploy them, I get the message "Deploy sucessfull". So far so good. I'm running it locally on http:// localhost:1880.

然后当我单击 Inject 节点或 Debug 节点时，它显示:错误:未部署注入节点"或错误:未部署调试节点".

Then when I click the Inject node or the Debug node, it says: "Error: Inject node not deployed" or "Error: Debug node not deployed".

有人知道如何解决这个错误吗?是服务器问题吗?

Anyone know how to fix this error? Is it a server problem?

推荐答案

遇到同样的问题并发现我正在处理的流程被禁用.当其选项卡上的字母为斜体并且在字母前面有一个对角线穿过它的圆圈时，您可以判断该流已禁用.双击流选项卡，将状态"更改为已启用".

Was having the same issues and discovered the flow that I was working on was disabled. You can tell the flow is disabled when the lettering on its tab is in italic and there is a circle with a diagonal line through it ahead of the lettering. Double click the flow tab and change "status" to "enabled".
