为什么Node.js调试无法在VS代码中运行？

Question

在vscode中调试nodejs时出现错误：无法连接到运行时进程，10,000毫秒后超时-（无法连接到目标） enter image description here

launch.json

{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.

"version": "0.2.0",
"configurations": [
    {
        "type": "node",
        "request": "launch",
        "name": "Launch Program",
        "skipFiles": [
            "<node_internals>/**"
        ],
        "program": "${workspaceFolder}\\server\\js.js"
    }
  ]
}

为什么会出现此错误？我该如何解决？
