hololens - MRTK 问题

问题描述

想知道是否有其他人遇到过这个问题。我正在使用 Unity 2019.4 和 Microsoft 的 MRTK 2.7.2 开发 HoloLens 应用程序。在设备上运行时收到以下消息：

Loading native plugins
  Loading MicStreamSelector.dll
  Loading Microsoft.MixedReality.SceneUnderstanding.dll
  Loading pdfrenderer.dll
  Loading GpuStats.dll
  Loading AudioPluginMicrosoftSpatializer.dll
  Loading AudioPluginMsHRTF.dll
  Loading PlaneFinding.dll
  Loading Microsoft.MixedReality.Input.dll
Plugins: Failed to load 'Microsoft.MixedReality.Input' because one or more of its dependencies could not be loaded. 
(Filename: C:\buildslave\unity\build\Runtime/Misc/Plugins.cpp Line: 247)

Plugins: 2nd attempt to load module with '.dll' extension manually appended ('Microsoft.MixedReality.Input.dll') also couldn't be found (or it's dependencies). 
(Filename: C:\buildslave\unity\build\Runtime/Misc/Plugins.cpp Line: 253)

在这些消息之后不久，我收到一个异常，这似乎是相关的，因为它包含一堆关于 Microsoft.MixedReality.Input 的内容：

任何人都知道为什么 Microsoft.MixedReality.Input.dll 不会加载？知道可能缺少什么依赖项吗？我在哪里可以找到依赖项列表？

谢谢你的帮助。
