MRTK V2.6.1 - 全新安装 mrtk 后获取 DirectoryNotFoundException

Question

我今天使用 MRTK 建立了一个新的 Unity 项目。我使用的是 Unity 2020.3.26 和 MRTK 2.6.1。我通过 Microsoft 混合现实功能工具 安装了 MRTK。安装后，像往常一样Microsoft/MRTK，我收到了无数错误。但是，我无法修复以下错误并且不知道该怎么做：

System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Users\[Username]\source\repos\[Folder]\Unity\[Folder]\Library\PackageCache\com.microsoft.mixedreality.toolkit.foundation@2a959d4b1c8c-1621237827345\SDK\Experimental\InteractiveElement\Examples\Scripts\CustomStateExample\KeyboardState'.

此外，我对 Microsoft 混合现实功能工具 如何安装 MRTK 感到有点困惑。安装后一切都在路径“/Packages”下是否正确？ “/Assets”下没有添加文件夹。而“Packages”下的文件可以被认为是“只读”的，所以我很困惑所有的东西都在那里。

我已经找到一些关于路径限制为 260 个字符的帖子，但查看错误有 243 个字符。这仍然是问题吗？

Answer 1

我在文档中看到已经有 2.7.3 版本，尽管 Microsoft Mixed Reality Feature Tool 根本没有显示。在设置中，您必须激活更新，然后您只会显示 2.6.1 以上的版本。随着 2.7.3 的安装错误消失了！无论如何，我请求未来 reader 不要忽略我关于导入 mrtk 文件到“/Packages”路径的问题。谢谢！
