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.
我用以下步骤解决了同样的问题
Removed package <package id="Microsoft.CodeDom.Providers.DotNetCompilerPlatform" version="2.0.1" targetFramework="net46" /> from package.config file.
Edit the .csproj project file and removed the below settings.
<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\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.2.0.1\build\net46\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" Text="$([System.String]::Format('$(ErrorText)', '..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.2.0.1\build\net46\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props'))" />
</Target>
Go to package manager console and run the command Update-Package –reinstall
第2点和第3点是其他用户提出的，我很感谢这些用户。第一点，从包中删除Microsoft.CodeDom.Providers.DotNetCompilerPlatform。配置文件更重要。此外，在运行第3点中提到的命令之后，问题就解决了。删除所有不需要的包并更新所需的包引用。
希望这能帮助到一些人。
为了在这里展开一些答案，是的，你可以从你的.csproj文件中删除以下块:
<目标
这解决了问题，但在我的情况下，我注意到我有额外的引用。net。编译器和。codedom。不同版本的供应商:
<Error Condition="!Exists('..\packages\Microsoft.Net.Compilers.1.0.0
<Error Condition="!Exists('..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\
<Error Condition="!Exists('..\packages\Microsoft.Net.Compilers.2.0.1
<Error Condition="!Exists('..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.3\
当我的包裹。配置仅参考以下内容:
<package id="Microsoft.Net.Compilers" version="2.0.1"
<package id="Microsoft.CodeDom.Providers.DotNetCompilerPlatform" version="1.0.3"
从.csproj文件中删除1.0.0项解决了这个问题。
