无法在mac上使用dotnet ef core搭建脚手架

我正在尝试使用.net内核从我MAC上的现有数据库中反向设计模型类。数据库在带有Windows的VM中运行，我可以从osx连接到它。

在我的project.json中，我有以下内容：

"dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.1",
      "type": "platform"
    },
    "Microsoft.AspNetCore.AngularServices": "1.0.0-*",
    "Microsoft.AspNetCore.Diagnostics": "1.0.0",
    "Microsoft.AspNetCore.Mvc": "1.0.1",
    "Microsoft.AspNetCore.Razor.Tools": {
      "version": "1.0.0-preview2-final",
      "type": "build"
    },

  },

    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final",
    "Microsoft.DotNet.Watcher.Tools": "1.0.0-preview2-final",
    "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final"
  },

  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ]
    }
  },

  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true,
    "compile": {
      "exclude": ["node_modules"]
    }
  }

但是当我跑步的时候

dotnet ef dbcontext scaffold "myDbConnectString" Microsoft.EntityFrameworkCore.SqlServer

我收到以下错误，我无法通过这个

我试图来回更改我的依赖项的版本，但没有结果。任何人有任何指针？
