使用最新版本的Firebase和节点v10在VSCode中本地调试Firebase函数

Question

[Web上似乎有很多@google-cloud/functions-emulator的示例，但现在已弃用。我浏览了最新的firebase文档Test functions interactively，在这里我们可以使用Shell在本地测试功能。

我尝试使用VSCode进行调试，但是每当我按下调试器按钮时，VSCode都会向我发出此警告，然后立即停止调试：

C:\Program Files\nodejs\node.exe --inspect-brk=46655 functions\lib\index.js 
Debugger listening on ws://127.0.0.1:46655/c8545176-06c0-4b95-80ec-bcba4ca9d90e
For help, see: https://nodejs.org/en/docs/inspector
Debugger attached.
Warning, FIREBASE_CONFIG and GCLOUD_PROJECT environment variables are missing. Initializing firebase-admin will fail
setup.js:53 

我也用ts / js代码初始化了管理对象，但是调试器也出现了同样的问题：

 const admin = require("firebase-admin");
if (!admin.apps.length)
    admin.initializeApp({
        projectId: "...",
        appId: "...",
        databaseURL: "...",
        storageBucket: "...",
        apiKey: "...",
        authDomain: "...",
        messagingSenderId: "...",
        measurementId: "..."
    });

VSCode launch.json

  "configurations": [
    {
      "type": "node",
      "request": "launch",

      "skipFiles": ["<node_internals>/**"],
      "program": "${file}",
      "outFiles": ["${workspaceFolder}/**/*.js"]
    }
  ]

}

firebase.json：

    "public": "_site",
    "ignore": ["firebase.json", "**/.*", "**/node_modules/**"],
    "functions": {
      "predeploy": [
        "npm --prefix \"$RESOURCE_DIR\" run lint",
        "npm --prefix \"$RESOURCE_DIR\" run build"
      ]
    },
    "rewrites": [
      {
        "source": "/bigben",
        "function": "bigben"
      },
      {
        "source": "**",
        "destination": "/index.html"
      }
    ],
    "cleanUrls": true
  }
}

平台：Windows 10节点：v10项目：具有Typescript功能的Firebase Web应用

firebase：7.8.1。

我想知道是否有可能在VSCode中放置断点并运行调试器以获取最新的Firebase函数。

Firebase CLI中的仿真器当前不支持此功能，但是正在使用该功能。您可以在这里阅读：
