1. 本地运行

npm install -g n8n
n8n start

2. 如何安装节点

https://docs.n8n.io/integrations/community-nodes/installation/

通过命令行安装npm package

https://docs.n8n.io/integrations/community-nodes/installation/manual-install/

打开n8n的nodes目录

windows:

C:\Users\pc.n8n\nodes

npm i n8n-nodes-nodeName

重启n8n

3. 自制n8n节点

package name starts with n8n-nodes-

• Include n8n-community-node-package in your package keywords.

文档：https://docs.n8n.io/integrations/creating-nodes/overview/

3.1 Node的文件结构

https://docs.n8n.io/integrations/creating-nodes/build/reference/node-base-files/structure/

一个node的文件结构

4. 如何断点调试node中的代码

启动时，要让node 监听调试端口

set NODE_OPTIONS=--inspect=9229
n8n start

检查 是否监听成功

netstat -ano | findstr :9229

Vscode中增加调试配置

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Attach n8n (9229)",
      "type": "node",
      "request": "attach",
      "port": 9229,
      "restart": true,
      "skipFiles": ["<node_internals>/**"]
    }
  ]
}

5. 注意事项

5.1 写文件异常

如果写需要写文件到本地目录，需要设置下面这个环境变量

set N8N_RESTRICT_FILE_ACCESS_TO="D:\downloads"

如果是docker

environment:
        N8N_RESTRICT_FILE_ACCESS_TO: "/shared;/home/node/.n8n-files"

否则写文件会提示

The file "D:\downloads\douyin_1769760258699.mp4" is not writable.
