Webpack 如何解决'；错误：您需要提供一个目标平台'；尝试设置网页包时

我是手机应用程序开发新手，正在尝试在我当前的手机应用程序中设置Webpack。我正在遵循Nativescript网站上的步骤。初始安装后，我收到1个警告和2个错误，如下所示：

我很难理解为什么找不到我的模块。我想我需要编辑我的webpack.config.js文件，但到目前为止还没有成功

在阅读在线帖子（当然还有webpack--help）后，我发现了以下命令： “$webpack--显示错误详细信息”
并在此处看到了一些附加信息：

错误详细信息告诉我提供一个目标平台。我尝试过将错误列表中的项目添加到appComponents数组中，但没有成功，也没有添加到webpack.config.js文件中的其他位置
