Offline Nuget Packages

I need to install Nuget Package ProductionStackTrace, so I use the following command

PM> Install-Package ProductionStackTrace

But when I execute this command I get the following error

The source at Microsoft Visual Studio Offline Packages [C:\Program Files (x86)\Microsoft SDKs\NuGetPackages] is unreachable.

I checked the path and yes the package is not there; isn't Nuget Package added by default? If not, from where I can add it?
