缺少NuGet包

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.

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'))" />

其他回答

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。

我的问题是NuGet不能自动获取/更新包，因为完整的文件路径太大了。通过将我的解决方案移动到我的文档中的一个文件夹而不是一个深度嵌套的文件夹来修复。

然后可以右键单击解决方案并选择“恢复NuGet包”(如果您只是构建它并让它为您完成它，这可能是不必要的)，然后选择“管理解决方案的NuGet包”以将所有包更新到最新版本。

这是从微软网站上下载的一个ASP MVC应用程序示例的解决方案。

我收到了这个令人沮丧的消息。最后对我有用的是删除/包内的所有文件和文件夹，让VS在下次构建时重新获取所有内容。

我通过从.csproj文件中删除这段代码来解决我的问题:

<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
  <PropertyGroup>
    <ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
  </PropertyGroup>
  <Error Condition="!Exists('$(SolutionDir)\.nuget\NuGet.targets')" Text="$([System.String]::Format('$(ErrorText)', '$(SolutionDir)\.nuget\NuGet.targets'))" />
</Target>

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.
