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.

对于DevOps/构建工程师，您可能可以针对受影响的SLN或缺乏SLN的项目修复此运行nuget恢复。我必须为我们所有UWP项目的CI/CD构建这样做。

Make sure nuget is installed on the build slave either in Visual Studio or standalone. If it's the latter, make sure it's in PATH and skip step 2. Either open the VS Dev CMD console, or load it via an already open one, which you can do with the instructions below: VS2015 call "%VS140COMNTOOLS%VsDevCmd.bat" or VS2017 call "%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Enterprise\Common7\Tools\VsDevCmd.bat" call nuget restore MyStuff.SLN or call nuget restore MyStuff.csproj if there's no SLN.

我正在使用VS2012，遇到同样的错误。我从.csproj文件中删除了下面的Target标记，它开始编译，没有出现任何错误。

<Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
  -- Error messages within Target Tag
</Target>

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。

遇到这个问题

按以下步骤求解

清除packages文件夹中的内容(先备份) 使用“更新-包-重新安装”从包管理控制台的NuGet中重新获取和重新安装包(Tools -> NuGet包管理器->包管理控制台) 从.csproj文件中删除冗余路径。注意:NuGet会添加新的路径到csproj文件，但它不会删除旧的路径… (有一些机会csproj文件有多个路径为同一文件)

为什么我们需要“Microsoft.Net.Compilers.props”? 它将提供“\roslyn”文件夹。如果没有它，你可能仍然可以编译程序，但不能使用@{html.RenderPartial…}

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。

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.
