Version error while installing nuget package for .net core class library

Question

I have created a nuget package for my .net core class library.

below is my Project.json code for my nuget packaged class library

{
  "dependencies": {
    "NETStandard.Library": "1.6.0",
    "Newtonsoft.Json": "9.0.1",
    "System.Collections.NonGeneric": "4.0.1",
    "System.Dynamic.Runtime": "4.0.11",
    "System.IO.FileSystem.Watcher": "4.0.0",
    "System.Runtime.Loader": "4.0.0",
    "System.Threading.Thread": "4.0.0"
  },

  "frameworks": {
    "netstandard1.6": {
      "imports": "dnxcore50"
    }
  },
  "version": "1.0.0-*"
}

When I try to install this nuget package in another class library ,I'm getting the below error.

Retrieving package 'JsonConfig.Core 1.0.0' from 'Local Packages'.

        <description>JsonConfig.Core is ported from JsonConfig by Timo Dörr. JsonConfig.Core is a simple to use configuration library, allowing JSON based config files for your C#/.NET Core application instead of cumbersome web.config/application.config xml files.

It is based on Newtonsoft.Json.Net and C# 4.0 dynamic feature. Allows putting your programs config file into .json files, where a default config can be embedded as a resource or put in the (web-)application folder. Configuration can be accessed via dynamic types, no custom classes or any other stub code is necessary.

JsonConfig brings support for config inheritance, meaning a set of configuration files can be used to have a single, scoped configuration at runtime which is a merged version of all provided configuration files.</description>

EDIT 1---

Below is the Project.json for the class library where I'm trying to install this package

{
  "version": "1.0.0-*",

  "dependencies": {
    "NETStandard.Library": "1.6.0"
  },

  "frameworks": {
    "netstandard1.6": {
      "imports": "dnxcore50"
    }
  }
}

Could somebody please help me fix this issue.

@Deilan Added the `project.json` of the other class library. Thanks. — Satish Kumar, Nov 15 '16 at 11:49
The problem is in dependency from `JsonConfig.Core` NuGet package. But I don't see it as a declared dependency anywhere among dependencies in the provided `project.json` files. Where do you reference it? Maybe somewhere in other project in the solution? — Deilan, Nov 15 '16 at 12:00
@Deilan I'm trying to install the package to add it as a reference. But I keep getting the above mentioned error. It is not working even if I add it manually under the Project.json. — Satish Kumar, Nov 15 '16 at 17:42
