Question

我试图开发一个具有Vuforia引擎功能的Unity项目，以将其部署到HoloLens。简短的问题摘要：不起作用。我首先使用Vuforia AR相机和放置在视场中的3D立方体创建了一个非常简单的项目，只是为了对其进行测试。它可以在Unity预览中显示它。但是，Unity控制台会出现错误，并且Unity程序不能在HoloLens上运行，也不能在Visual Studio预览中作为独立应用程序运行。经常发生的一种错误是：

DllNotFoundException：VuforiaWrapper。

可以在Visual Studio中构建一个独立的应用程序，该应用程序应显示3D立方体，但是背景为黑色，相机无法正常工作（Razer Kiyo）。

我尝试了多个Unity版本，其中包括2017年和2018年的LTS版本以及Visual Studio 2017年和2019年。它不适用于以上任何一个版本。

将Vuforia Hololens示例导入Unity会使该项目崩溃，并使其对于我尝试过的每个Unity版本都无法编译，因此我不得不放弃这一点。

有人知道如何解决吗？对于这样一个简单的项目甚至不起作用，这似乎很奇怪。

从附加的Visual Studio版本中查找日志文件：

错误DllNotFoundException: VuforiaWrapper表示Unity正在尝试加载dll，但是DLL似乎不存在于正在加载的位置。

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

您是否已检查路径“ 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计算机上的本地运行，因此您应该能够仅检查目录。

通常，当我看到dll找不到错误时，是因为我的插件dll配置不正确。检查plugin documentation并再次检查是否已将vuforia dll配置为部署在您的计算机体系结构和HoloLens体系结构（x86）上。
