Windows的Cordova构建失败

Question

我想在Windows / Windows Mobile上测试我的应用程序。 为此，我首先安装了Visual Studio Community 2017 ，然后下载了Windows 10 SDK & Mobile Development with JavaScript 。 之后，我添加了Windows平台，并在config.xml中添加了两行代码，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"我正面临以下错误

Configuration : debug
Platform      : x64
Patching 10 in prebuild event...

什么东西少了？
