Question

大家好我在ASP.NET Core上的项目中遇到EFCore迁移的问题。一些技术信息：操作系统：macOS

dotnet --version 1.0.0-preview2-003148

这是我的project.json：

{
  "dependencies": {
    "Microsoft.NETCore.App": {
      "version": "1.0.1",
      "type": "platform"
    },
    "Microsoft.AspNetCore.Mvc": "1.0.1",
    "Microsoft.AspNetCore.Routing": "1.0.1",
    "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.1",
    "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0",
    "Microsoft.Extensions.Configuration.FileExtensions": "1.0.0",
    "Microsoft.Extensions.Configuration.Json": "1.0.0",
    "Microsoft.Extensions.Configuration.CommandLine": "1.0.0",
    "Microsoft.Extensions.Logging": "1.1.0-preview1-final",
    "Microsoft.Extensions.Logging.Console": "1.1.0-preview1-final",
    "Microsoft.Extensions.Logging.Debug": "1.1.0-preview1-final",
    "Microsoft.Extensions.Options.ConfigurationExtensions": "1.0.0",
    "Microsoft.EntityFrameworkCore": "1.1.0-preview1-final",
    "Microsoft.Extensions.Logging.Abstractions": "1.1.0-preview1-final",
    "Npgsql.EntityFrameworkCore.PostgreSQL": "1.0.2",
    "Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview3-final",
    "Microsoft.EntityFrameworkCore.Design": {
      "type": "build",
      "version": "1.1.0-preview1-final"
    },
    "Npgsql.EntityFrameworkCore.PostgreSQL.Design": "1.0.2"
  },
  "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final",
    "Microsoft.EntityFrameworkCore.Tools": {
      "version": "1.0.0-preview3-final",
      "imports": [
        "portable-net45+win8+dnxcore50",
        "portable-net45+win8"
      ]
    }
  },
  "frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ],
      "buildOptions": {
        "emitEntryPoint": true
      }
    }
  },
  "buildOptions": {
    "emitEntryPoint": true,
    "preserveCompilationContext": true
  },
  "runtimeOptions": {
    "configProperties": {
      "System.GC.Server": true
    }
  },
  "publishOptions": {
    "include": [
      "wwwroot",
      "**/*.cshtml",
      "appsettings.json",
      "web.config"
    ]
  },
  "scripts": {
    "postpublish": [
      "dotnet publish-iis --publish-folder %publish:OutputPath% --framework %publish:FullTargetFramework%"
    ]
  },
  "tooling": {
    "defaultNamespace": "TTT"
  }
}

我从project.json文件夹中启动“dotnet ef”命令。

我的行动：

1）dotnet restore

2）dotnet ef

之后我收到此错误：“找不到匹配命令”dotnet-ef“。

的可执行文件

我在Program类（Program.cs）中有静态“Main”方法。

有没有人知道我做错了什么？

感谢。

Answer 1

您需要将"Microsoft.EntityFrameworkCore.Tools.DotNet": "1.0.0-preview3-final"添加到工具部分。

有关详细信息，请参阅https://blogs.msdn.microsoft.com/dotnet/2016/10/25/announcing-entity-framework-core-1-1-preview-1/

Answer 2

版本1.1.0今天发布，因此True中添加的正确版本为project.json：

1.1.0-preview4-final

EF Core 1.1 preview1：找不到匹配命令“dotnet-ef”的可执行文件
