Node.js 无法调试VSCode上的Typescript

我试图在Windows 10上使用WSL作为默认shell从vscode调试一个typscript项目，但在单击“运行”按钮时出现以下错误

The terminal process "C:\WINDOWS\System32\wsl.exe -e npm run build" failed to launch (exit code: 1).

我做错了什么

.vscode/launch.json

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

                "${workspaceFolder}/dist/**/*.js"
            ]
        }

tsconfig.json

    "./**/config*.json"
  ],
  "exclude": [ 
    "./dist/**/*",

  ]
}

package.json中所有与npm相关的命令，如

npm build

，

npm start

等，都可以在shell中正常工作
