I was attempting to restructure (filesystem-wise) a Visual Studio solution a little bit, and this solution uses an external library (specifically, Onnx Runtime; I use the NuGet OnnxRuntime Visual Studio extension Microsoft.ML.OnnxRuntime v1.12.0).

我试图稍微重组（文件系统方面）Visual Studio解决方案，该解决方案使用外部库（特别是Onnx Runtime；我使用NuGet OnnxRuntime Visual Studio扩展Microsoft.ML.OnnxRuntime v1.12.0）。

After restructuring, I took a look in the .vcxproj files of the various projects in my solutions, and ensured everything looked well, which it all seemed to.

重组后，我查看了解决方案中各个项目的.vcxproj文件，并确保一切看起来都很好。

When I try to build the project, however, I get this error:

然而，当我尝试构建项目时，我会遇到以下错误：

Error C1083 Cannot open include file: 'onnxruntime_cxx_api.h': No such file or directory

错误C1083无法打开包含文件：“onnxruntime_cxx_api.h”：没有这样的文件或目录

However, if I Ctrl+left click the include directive that causes this error (or alternatively: right click and choose "Go To Document"), it does manage to find it. The path of the opened file is: $(SolutionDir)\packages\Microsot.ML.OnnxRuntime.1.12.0\build\native\include\onnxruntime_cxx_api.h

(Where $(SolutionDir) is substtuted with the actual path to my solution file.)

（其中$（SolutionDir）被替换为我的解决方案文件的实际路径。）

My solution structure is a bit strange:

我的解决方案结构有点奇怪：

./solution/
    ./solution.sln
    ./packages/
        ./Microsoft.ML.OnnxRuntime.1.12.0/
            ...
    ./sources/
        ./projectA/
            projectA .cpp and .hpp files
        ./projectB/
            projectB .cpp and .hpp files
    ./vs_stuff/
        ./projectA/
            projectA Visual Studio files (vcxproj, vcxproj.users, packages.config, ...)
        ./projectB/
            projectB .cpp and .hpp files (vcxproj, vcxproj.users, packages.config, ...)

I looked at all of the vs_stuff files and made sure that they do indeed point to the appropriate paths, and as far as I could tell, they do.

我查看了所有的vs_stuff文件，并确保它们确实指向了适当的路径，而且据我所知，它们确实指向。

Potentially crucial detail: this all started after I had attempted to restructure my solution. Initially it was the classic ./solution dir containing separate project directories, each with both sources and VS-related stuff; due to various requirements I had to change it to the structure described above, and the error resulted from this.

潜在的关键细节：这一切都是在我试图重组我的解决方案之后开始的。最初它是经典/解决方案目录包含单独的项目目录，每个目录都有源和VS相关的内容；由于各种要求，我不得不将其更改为上述结构，而错误就是由此产生的。

How might I go about solving this? The only thing I could think to do was to manually add

我该如何解决这个问题？我唯一能想到的就是手动添加

$(SolutionDir)\packages\Microsot.ML.OnnxRuntime.1.12.0\build\native\include

to my include directories or something, but that seems excessive and ugly and wasn't necessary before; plus, the IDE does find the header, so I'm not sure why the compiler doesn't.

我的include目录或其他什么，但这似乎太过分和丑陋了，以前没有必要；另外，IDE确实找到了头，所以我不知道编译器为什么找不到。

The directory is added automatically by NuGet.
Please check if there is

该目录由NuGet自动添加。请检查是否有

$(MSBuildThisFileDirectory)../../build/native/include/;

You may have inadvertently modified the configuration. When I moved the vcxproj file location, the line didn't exist anymore.

您可能无意中修改了配置。当我移动vcxproj文件位置时，该行已不存在。

To fix the problem:

要解决此问题，请执行以下操作：

1.Reinstall the Microsoft.ML.OnnxRuntime package.

1.重新安装Microsoft.ML.OnnxRuntime包。

2. Now you may get a NuGet package error. Open the vcxproj file with text.
   There will be multiple lines (at least 3) like '..\packages\Microsoft.ML.OnnxRuntime.1.12.0\build\native\Microsoft.ML.OnnxRuntime.targets. Delete them. And there are already right directories next to them
   <ImportProject="..\..\packages\Microsoft.ML.OnnxRuntime.1.12.0\build\native\Microsoft.ML.OnnxRuntime.props"
