Notepad++ NppMarkdownPanel 插件从现成的源组装不成功

我没有更改插件源代码。我问了插件的作者https://github.com/mohzy83/NppMarkdownPanel/issues/13但他写道构建是成功的。那为什么会有警告呢？

Notepad++ 本身不会引诱内置插件：

也许我没有安装一些组件？这是我的 visual-studio-2017 配置文件：

    {
        "version": "1.0",
        "components": [
            "Microsoft.VisualStudio.Workload.ManagedDesktop",
            "Microsoft.VisualStudio.Workload.NativeDesktop",
            "microsoft.net.componentgroup.targetingpacks.common",
            "microsoft.componentgroup.blend",
            "microsoft.visualstudio.component.entityframework",
            "microsoft.visualstudio.component.debugger.justintime",
            "microsoft.visualstudio.component.vc.tools.x86.x64",
            "microsoft.visualstudio.componentgroup.nativedesktop.winxp",
            "microsoft.visualstudio.component.vc.140",
            "microsoft.visualstudio.component.diagnostictools"
        ]
    }

从这个文件中，您可以找出组装需要哪些组件？
