我正在使用ASP.Net Core RC2 Microsoft.EntityFramework.Core和SQLite 来做项目示例.

我已经按照本教程:https: //damienbod.com/2015/08/30/asp-net-5-with-sqlite-and-entity-framework-7/

但是,当我运行此命令时:

dotnet ef migrations add FirstMigration

我收到了这个错误:

No executable found matching command "dotnet-ef"

这是我的project.json配置:

    "Microsoft.NETCore.App": {
