我试图开发一个带有 Vuforia 引擎功能的 Unity 项目以部署到 HoloLens。简短的问题摘要：它不起作用。我开始使用 Vuforia AR 相机和放置在视野中的 3D 立方体创建一个非常简单的项目，只是为了测试它。它可以在 Unity 预览中呈现它。然而，Unity 控制台出现错误，Unity 程序既不能在 HoloLens 上运行，也不能作为 Visual Studio 预览中的独立应用程序运行。总是发生的一个错误是：

DllNotFoundException：VuforiaWrapper。

可以在 Visual Studio 中构建一个独立的应用程序，它会按应有的方式呈现 3D 立方体，但背景是黑色的，相机不工作（Razer Kiyo）。

我已经尝试了几个 Unity 版本，包括 2017 和 2018 的 LTS 版本以及 Visual Studio 2017 和 2019。它不适用于上述任何一个版本。

将 Vuforia Hololens 样本导入 Unity 会破坏项目，并使其无法在我尝试过的每个 Unity 版本中编译，因此我不得不放弃它。

有人知道如何解决这个问题吗？它甚至不适用于这样一个简单的项目，这似乎很奇怪。

从附加的 Visual Studio 构建中查找日志文件：

该错误DllNotFoundException: VuforiaWrapper表明 Unity 正在尝试加载 dll，但加载的位置似乎不存在 DLL。

阅读错误，有很多形式：

Fallback handler could not load library C:/Visual Studio Projects/UnityHololens2018_4_11VuforiaUpdate8_5_8_64_86_Test1/build/bin/UnityHololens2018_4_11TestVuforiaUpdate8_5_8_Data/Mono/VuforiaWrapper.dll

您是否检查了路径“C:/Visual Studio Projects/UnityHololens2018_4_11VuforiaUpdate8_5_8_64_86_Test1/build/bin/UnityHololens2018_4_11TestVuforiaUpdate8_5_8_Data/Mono”以验证文件是否存在？似乎该错误消息来自您的计算机上本地运行，因此您应该能够检查目录。

通常当我看到 dll not found 错误时，这是​​因为我的插件 dll 配置不正确。检查插件文档并仔细检查 vuforia dll 是否配置为部署在您的机器架构和 HoloLens 架构（即 x86）上。
