C# Offline EntityFramework Installation

Every time I tried to install the EntityFramework offline, I faced the error messages which are given ahead. The offline command was as given below.

Install-Package EntityFramework -Source G:\Resources\Nuget-Packages\

which was based on the following syntax

Install-Package <PackageName> -Source <PackagePath>

The issue was solved when I unchecked the Package Sources.

Error Message.
