我对使用Cluster的Visual Studio 代码有一些问题
编辑
如果我按 Ctrl + F5它可以正常工作，除了F5之外它还在做什么，我是否需要始终使用 Ctrl 启动命令？
---
当使用 VS Code Launch 命令(F5)启动时，似乎工作人员永远不会启动。我是否需要对 .vscode/launch.json 文件进行一些更改以使集群正常工作。
实际代码复制自 Node.js 6 api https://nodejs.org/api/cluster.html#cluster_cluster
npm test Windows 命令提示符显示：
Master started
Listening port 80
Listening port 80
Listening port 80
Listening port 80
VS Code (F5)调试控制台显示：
node --debug-brk=7601 --nolazy index.js
Debugger listening on port 7601
Master started
Debugger listening on port 7602
Debugger listening on port 7603
Debugger listening on port 7604
Debugger listening on port 7605
