无法在 HoloLens 2 上构建和 运行 Unity 应用程序
Unable to build and run Unity application on HoloLens 2
我正在尝试使用 Unity 构建我的第一个 HoloLens 应用程序。我导入了 MRTK 及其功能。我还通过 USB 连接了 HoloLens。只要我按下“Build and 运行”，它就会提供 3 个错误。我的通用 Windows 平台构建设置如下：
- 目标设备：HoloLens，
- 架构师：ARM（我也试过ARM64），
- 构建类型：D3D 项目，
- 目标 SDK 版本：最新安装，
- 最低平台版本：（所有版本都给出相同的错误），
- Visual Studio 版本：最新安装，
- 构建并 运行 于：USB 设备，
- 构建配置：发布。
无论构建设置如何，按下“Build and 运行”后立即出现以下错误：

从构建日志来看，“Windows Phone Player 运行ner”相关的输出应该是由两个可能的原因引起的：
- Unity 版本不正确。
- 构建并运行：USB 设备 设置
对于Unity版本，我们建议使用Unity 2020 LTS版本进行HoloLens 2开发：https://unity3d.com/unity/qa/lts-releases?version=2020.3
对于 Build 和 运行 on 设置，问题是由 Build 和 运行 on: USB Device 设置引起的，这是一个已知的 issue 并且不会被 Unity 修复。最佳做法是，请切换到 Local Machine 并生成 Visual Studio 项目。在 Visual Studio 的帮助下，您可以通过无线网络或 USB 数据线部署到 HoloLens 2。参见：
