Javascript Firebase部署错误：找不到模块'@babel/runtime/helpers/builtin/interopRequireDefault'；

我正在尝试部署firebase函数，但我遇到了很多问题，这让我很为难

当我尝试将应用程序部署到firebase时，我会遇到babel错误，如：

i  deploying functions, hosting
i  functions: ensuring necessary APIs are enabled...
✔  functions: all necessary APIs are enabled
i  functions: preparing functions directory for uploading...
i  functions: packaged functions (56.91 KB) for uploading
✔  functions: functions folder uploaded successfully
i  hosting: preparing dev directory for upload...
✔  hosting: 4 files uploaded successfully
i  functions: updating function main...
⚠  functions[main]: Deployment error.
Function load error: Code in file index.js can't be loaded.
Did you list all required modules in the package.json dependencies?

项目文件夹根目录中的package.json：

  "scripts": {
    "babel": "babel src -d functions/src && babel index.js -d functions"
  },

    "firebase-tools": "^3.19.1",
    "webpack": "^4.14.0",
    "webpack-dev-server": "^3.1.4"
  }
}

编写完代码后，我运行

npm run babel

转换代码并将其放入functions文件夹。然后运行

firebase部署

那么，是什么导致了此错误？

在部署时也有问题，但通过安装解决了此问题

@babel/runtime 

作为“函数”文件夹中的依赖项

@babel/runtime
