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.

当从Git部署时，我在Azure中失败地构建了这个问题。

原来我的.gitignore从..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.2.0.0\build\net46\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props中排除了build文件夹。

一旦构建文件夹(强制)提交到Git，问题就解决了。

注释掉.csproj中的以下代码

<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
<PropertyGroup>
  <ErrorText>This project references NuGet package(s) that are missing on this computer. Use 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('..\packages\Costura.Fody.2.0.1\build\Costura.Fody.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\Costura.Fody.2.0.1\build\Costura.Fody.targets'))" />
<Error Condition="!Exists('..\packages\Fody.3.1.3\build\Fody.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\Fody.3.1.3\build\Fody.targets'))" />

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。

我今天也犯了同样的错误(丢失了完全相同的包裹)。我还创建了一个MVC + Web API项目。

发生这种情况是因为我将应用程序文件(包括.csproj)文件移动到另一个位置。我手动更新了.sln文件，但所有包依赖项现在(Visual Studio 2015)存储在.csproj文件中。

编辑.csproj文件并更正解决方案文件夹(其中包含packages文件夹)的相对路径，为我解决了这个问题。

如果使用package，也会得到这个错误。与此构建命令一起配置

MSBuild.exe /t:Restore MySln.sln

在这种情况下，要么切换到nuget恢复命令，要么使用PackageReference。

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.
