Question

当我使用命令

时

dnx ef

发生以下错误：

C：\ Users \ Livio \ OneDrive \ Informatik \ Websites \ HomeNetwork \ src \ HomeNetwork.API＆gt; dnx ef System.ArgumentNullException：值不能为null。参数名称：appEnv at Microsoft.Data.Entity.Utilities.Check.NotNull [T]（T value，String parameterName）在Microsoft.Data.Entity.Commands.Program..ctor（IServiceProvider＆gt; serviceProvider，IApplicationEnvironment appEnv，ILibraryManager libraryManager，＆gt; IRuntimeEnvironment runtimeEnv）

我正在使用dnvm 1.0.0-beta8 coreclr x86。

我的project.json看起来像这样（在HomeNetwork.API中）

{
  "webroot": "wwwroot",
  "version": "1.0.0-*",

  "dependencies": {
    "Microsoft.AspNet.Mvc": "6.0.0-beta5",
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta5",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta5",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta5",
    "EntityFramework.SqlServer": "7.0.0-beta5",
    "EntityFramework.Commands": "7.0.0-beta5"
  },

  "commands": {
    "web": "Microsoft.AspNet.Hosting --config hosting.ini",
    "ef": "EntityFramework.Commands"
  },

  "frameworks": {
    "dnx451": { },
    "dnxcore50": { }
  },

  "exclude": [
    "wwwroot",
    "node_modules",
    "bower_components"
  ],
  "publishExclude": [
    "node_modules",
    "bower_components",
    "**.xproj",
    "**.user",
    "**.vspscc"
  ]
}

我在没有编辑代码的情况下创建了这个项目，期望添加EF7依赖项。

Answer 1

我正在使用dnvm 1.0.0-beta8 coreclr x86。

然后，您应该使用beta8版本的依赖项：

"dependencies": {
    "Microsoft.AspNet.Mvc": "6.0.0-beta8",
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta8",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta8",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta8",
    "EntityFramework.SqlServer": "7.0.0-beta8",
    "EntityFramework.Commands": "7.0.0-beta8"
  }

EF7：dnx ef命令错误“值不能为空”
