如何在Visual Studio Code for React Native中设置调试？

问：

我搜索了，但除了 Visual Studio Code 文档之外，我找不到任何外部资源，并且仅仅遵循这些文档不允许我在 iOS 和 Android 中调试 React Native 应用程序。

我不断收到错误消息（对于Android，对于iOS，是类似的：

[vscode-react-native][警告]无法在 http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false&minify=false 导入脚本。 调试不起作用：尝试从应用内部重新加载 JS，或者 重新连接 VS Code 调试器：path 必须为字符串

我的文件为：launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug Android",
            "program": "${workspaceRoot}/.vscode/launchReactNative.js",
            "type": "reactnative",
            "request": "launch",
            "platform": "android",
            "internalDebuggerPort": 9090,
            "sourceMaps": true,
            "outDir": "${workspaceRoot}/.vscode/.react"
        },
        {
            "name": "Debug iOS",
            "program": "${workspaceRoot}/.vscode/launchReactNative.js",
            "type": "reactnative",
            "request": "launch",
            "platform": "ios",
            "target": "iPhone 6s",
            "internalDebuggerPort": 9090,
            "sourceMaps": true,
            "outDir": "${workspaceRoot}/.vscode/.react"
        },
        {
            "name": "Attach to packager",
            "program": "${workspaceRoot}/.vscode/launchReactNative.js",
            "type": "reactnative",
            "request": "attach",
            "internalDebuggerPort": 9090,
            "sourceMaps": true,
            "outDir": "${workspaceRoot}/.vscode/.react"
        },
        {
            "name": "Debug in Exponent",
            "program": "${workspaceRoot}/.vscode/launchReactNative.js",
            "type": "reactnative",
            "request": "launch",
            "platform": "exponent",
            "internalDebuggerPort": 9090,
            "sourceMaps": true,
            "outDir": "${workspaceRoot}/.vscode/.react"
        }
    ]
}

我正在尝试在 iOS 模拟器和 Android 设备中进行调试，但该过程从未附加到外部 JS 调试器。
