This project references NuGet package(s) that are missing on this computer
Solution 1
In my case, I had to remove the following from the .csproj file:
<Import Project="$(SolutionDir)\.nuget\NuGet.targets" Condition="Exists('$(SolutionDir)\.nuget\NuGet.targets')" />
<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>
In fact, in this snippet you can see where the error message is coming from.
I was converting from MSBuild-Integrated Package Restore to Automatic Package Restore (http://docs.nuget.org/docs/workflows/migrating-to-automatic-package-restore)
Solution 2
One solution would be to remove from the .csproj file the following:
<Import Project="$(SolutionDir)\.nuget\NuGet.targets" Condition="Exists('$(SolutionDir)\.nuget\NuGet.targets')" />
<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>
How?
- Right click on project. Unload Project.
- Right click on project. Edit csproj.
- Remove the part from the file. Save.
- Right click on project. Reload Project.

In my case it happened after I moved my solution folder from one location to another, re-organized it a bit and in the process its relative folder structure changed.
So I had to edit all entries similar to the following one in my .csproj
file from
<Import Project="..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets" Condition="Exists('..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" />
to
<Import Project="packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets" Condition="Exists('packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" />
(Note the change from ..\packages\
to packages\
. It might be a different relative structure in your case, but you get the idea.)

I easily solve this problem by right clicking on my solution and then clicking on the Enable NuGet Package Restore option
(P.S: Ensure that you have the Nuget Install From Tools--> Extensions and Update--> Nuget Package Manager for Visual Studio 2013. If not install this extention first)
Hope it helps.
Solution 5
In my case it had to do with the Microsoft.Build.Bcl version. My nuget package version was 1.0.21, but my project files were still pointing to version 1.0.14
So I changed my .csproj files from:
<Import Project="..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets" Condition="Exists('..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" />
<Target Name="EnsureBclBuildImported" BeforeTargets="BeforeBuild" Condition="'$(BclBuildImported)' == ''">
<Error Condition="!Exists('..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" Text="This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them. For more information, see http://go.microsoft.com/fwlink/?LinkID=317567." HelpKeyword="BCLBUILD2001" />
<Error Condition="Exists('..\..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" Text="The build restored NuGet packages. Build the project again to include these packages in the build. For more information, see http://go.microsoft.com/fwlink/?LinkID=317568." HelpKeyword="BCLBUILD2002" />
</Target>
to:
<Import Project="..\..\packages\Microsoft.Bcl.Build.1.0.21\build\Microsoft.Bcl.Build.targets" Condition="Exists('..\..\packages\Microsoft.Bcl.Build.1.0.21\build\Microsoft.Bcl.Build.targets')" />
<Target Name="EnsureBclBuildImported" BeforeTargets="BeforeBuild" Condition="'$(BclBuildImported)' == ''">
<Error Condition="!Exists('..\..\packages\Microsoft.Bcl.Build.1.0.21\build\Microsoft.Bcl.Build.targets')" Text="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=317567." HelpKeyword="BCLBUILD2001" />
<Error Condition="Exists('..\..\packages\Microsoft.Bcl.Build.1.0.21\build\Microsoft.Bcl.Build.targets')" Text="The build restored NuGet packages. Build the project again to include these packages in the build. For more information, see http://go.microsoft.com/fwlink/?LinkID=317568." HelpKeyword="BCLBUILD2002" />
And the build was working again.

I have an ASP.NET MVC5 application that worked yesterday and now I am getting this error when I try to build:
This project references NuGet package(s) that are missing on this computer.
I have the two options checked that allow nuget to automatically download and install missing packages checked / turned ON. I have also tried deleting all of the files in the packages folder and then have nuget re-download them. Also when I open nuget and look for updates it says there are none that need to be installed. I can't figure what else to do to move beyond this amazingly annoying issue.
I have also enabled nuget restore by right clicking the project and selecting that option. It then added a nuget folder and three items in that folder and does nothing to resolve the problem. I've tried re-building and still get the same error.
