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.

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.

对于nuget引用，我们可以通过引用或通过包添加a。配置文件。

在Visual Studio 2017中，字母顺序或nuget引用由VS自动处理。

但是在Visual Studio 2019中。如果你的nuget引用不是按字母顺序排列的，那么VS就不要在引用文件夹中加载文件。

为了解决这个问题。——删除.csproj/vbproj或package.config中的所有引用。

——保存在记事本中。尝试通过Nuget包管理器添加这些。

第一次试试。一旦安装。

—右键单击解决方案->恢复所有nuget包。

-你会看到它加载了一个nuget引用。

——现在一个一个做。

——如果你100%确定你的参考文献是按字母顺序排列的。只需将它们全部粘贴到.csproj/vbproj或package.config中即可。

—恢复溶液中的所有核。

你会看到所有的符号都将被加载。在解决方案资源管理器的顶部图标刷新你的引用文件夹。

快乐的引用。

我通过从.csproj文件中删除以下代码解决了这个问题

<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('..\..\..\Assemblies\NuGet\SpecFlow.Plus.Excel.1.4.2\build\SpecFlow.Plus.Excel.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\..\..\Assemblies\NuGet\SpecFlow.Plus.Excel.1.4.2\build\SpecFlow.Plus.Excel.targets'))" />

在我的案例中工作的解决方案- Visual Studio 2015 enterprise，项目.NET 4.6.1

升级至Update 3 安装Web开发工具

正如许多人建议的那样，删除<Target>标记可以使其可编译。然而，当您为测试项目这样做时，要注意它有一个副作用。

我得到了与MSTest相关的错误。TestAdapter nuget包在编译时。通过移除<Target>标签解决了这个问题。尽管它使构建成功，但测试方法变得不可发现。测试资源管理器不会列出该项目中的测试方法，运行测试或调试测试也不能很好地工作。

我在使用Visual Studio 2017和.Net框架4.7时遇到了这种情况，在其他版本中也很可能发生这种情况

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>
