我想在Windows / Windows Mobile上测试我的应用。为此，我首先安装了Visual Studio Community 2017，然后我下载了Windows 10 SDK & Mobile Development with JavaScript。之后我添加了Windows平台，以及config.xml中的两行代码，如下所示
<preference name="windows-target-version" value="10.0" />
<preference name="windows-phone-target-version" value="10.0" />
<engine name="windows" spec="5.0.0" />
现在，当我运行ionic cordova build windows -- --arch="x64"时，我面临以下错误
Configuration : debug
Platform : x64
