-在低于 Node.js 7.x 版本中，**只能在 Terminal 手动执行 `npm run debug`**， 然后通过以下配置进行 attach :
-
-```js
-// .vscode/launch.json
-{
-  "version": "0.2.0",
-  "configurations": [
-    {
-      "name": "Attach Egg Worker",

+      "port": 9229,

   ]
 }
 ```
 
-> 后续我们会提供一个 [vscode-eggjs](https://github.com/eggjs/vscode-eggjs) 来简化配置。
