我研究了这个问题,但没有一个解决办法有效。我安装了Visual Studio Professional 2015,我正在使用TFS。我的NuGet版本是3.1.6。这个问题只发生在我的c# Web API/MVC项目中。

我得到以下错误:

这个项目引用了NuGet包(s),这是缺失的 电脑。使用NuGet包还原来下载它们。更多的 信息,见http://go.microsoft.com/fwlink/?LinkID=322105。的 丢失的文件是 . . \ \ Microsoft.Net.Compilers.1.0.0 \制造\ Microsoft.Net.Compilers.props包

I do not have .nuget folder in my solutions. I have a packages folder in the solution and when I delete it, it seems like NuGet does rebuild the dependencies but the project still has the above error. I tried removing the project from TFS and it didn't fix it. Along with the above error, all the references in the project have yellow warning signs and say they are missing. When I checked the NuGet Package Manager for the project, everything that is "missing" has a green tick next to it, including Microsoft.Net.Compilers. I tried adding a new Web API/MVC project and it faced a similar problem where most references such as Owin were "missing" with the yellow warning sign.


当前回答

对我来说,包在正确的路径下,但是包文件夹中的构建文件夹不是。我只是删除了它所说的所有丢失的包并重新构建解决方案,它成功地创建了构建文件夹和.props文件。所以错误消息是正确的,它告诉我有什么东西漏了。

其他回答

Not sure if this will help anyone, but I had this issue come up when I deleted the source code from my local machine without having ever saved the solution file to TFS. (During initial development, I was right-clicking and checking in the project in Solution Explorer, but forgot to ever check in the solution itself.) When I needed to work on this again, all I had in TFS was the .csproj file, no .sln file. So in VS I did a File --> Source Control --> Advanced -- Open from Server and opened the .csproj file. From there I did a Save All and it asked me where I wanted to save the .sln file. I was saving this .sln file to the project directory with the other folders (App_Data, App_Start, etc.), not the top level directory. I finally figured out that I need to save the .sln file up a directory from the project folder so it's on the same level as the project folder. All my paths resolved and I was able to build it again.

解决方案中的文件夹名为”。网络项目”。通过将其重命名为“NET Project”,一切都很正常。所以一开始的点是个坏主意。

提比柳是正确的。我不得不编辑我的.csproj文件,因为文件被移动了,导致了这个问题

 <Import Project="..\..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.1\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props" Condition="Exists('..\..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.1\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" />

我改变了文件的顶部和底部

<Error Condition="!Exists('..\..\packages\Microsoft.Net.Compilers.1.0.0\build\Microsoft.Net.Compilers.props')" Text="$([System.String]::Format('$(ErrorText)', '..\..\packages\Microsoft.Net.Compilers.1.0.0\build\Microsoft.Net.Compilers.props'))" />
<Error Condition="!Exists('..\..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.1\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" Text="$([System.String]::Format('$(ErrorText)', '..\..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.1\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props'))" />

对我来说,问题是当我将解决方案复制到一个新文件夹并打开它时,它缺少如下所示的Nuget文件夹。我复制了这个文件夹,一切正常。注意:这个文件夹在我们的源代码控制中,但不在这个解决方案项目中,它在上面一个目录中。

这两个答案的组合对我来说是有效的。首先,我修改了.csproj文件以删除对1.0.0版本的引用

< Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild" >

  ----Error---

< /Target>

然后真的

Update-Package -Reinstall

它成功了。
