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.

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'))" />

对于在这里遇到我遇到的问题(在构建服务器上恢复了一些包，但不是所有包)的任何人来说，对我来说，难题的最后一块是添加NuGet。config在我的解决方案的根文件中，是. sln文件的兄弟，正如David Ebbo在这里解释的:http://blog.davidebbo.com/2014/01/the-right-way-to-restore-nuget-packages.html。

从Ebbo的博客文章来看，文件内容对我来说很简单

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://www.nuget.org/api/v2/" />
  </packageSources>
</configuration>

更新:

v3的NuGet API URL已更改(截至2016年9月)。从https://www.nuget.org/

<add key="nuget.org" value="https://api.nuget.org/v3/index.json" />

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>

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

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.
