我正在尝试在 ASP.NET 5 网站中使用 SQLite，但在使用 EntityFramework.Sqlite 和 Microsoft.Data.Sqlite 包时遇到问题。kpm restore 命令给了我：

并 kpm build给我：

Unable to resolve dependency EntityFramework.Sqlite 7.0.0-rc1-final
Unable to resolve dependency Microsoft.Data.Sqlite 1.0.0-rc1-final

但是，当我从 Visual Studio 构建并从我的 .dnx\packages 目录中获取包时，它运行良好：

Using Package dependency EntityFramework.Sqlite 7.0.0-rc1-final
Source: C:\Users\jerom\.dnx\packages\EntityFramework.Sqlite\7.0.0-rc1-final
File: lib\net451\EntityFramework.Sqlite.dll
Using Package dependency Microsoft.Data.Sqlite 1.0.0-rc1-final 3>     
Source: C:\Users\jerom\.dnx\packages\Microsoft.Data.Sqlite\1.0.0-rc1-final
File: lib\net451\Microsoft.Data.Sqlite.dll

如果我将--packages选项与kpm restore命令一起使用，它似乎可以工作：

kpm restore --packages C:\Users\jerom\.dnx\packages
Restoring packages for C:\Users\jerom\Documents\Visual Studio 2015\Projects\TongyiFapiao\src\TongyiFapiao\project.json
Resolving complete, 732ms elapsed
Restore complete, 738ms elapsed

但最后，当我执行时它失败了

k ef migration add initial
k ef migration apply

这是我的 project.json 文件：

{
    "version": "1.0.0-*",
    "compilationOptions": {
    "emitEntryPoint": true
},
"dependencies": {
    "Microsoft.AspNet.IISPlatformHandler": "1.0.0-rc1-final",

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

我尝试修改 Nuget.config 文件以使用不同的 Nuget 存储库，但它们都不起作用。我还升级了我的 KVM 和 DNVM，以下是安装的所有 .NET 版本：

C:\Users\jerom\Documents\Visual Studio 2015\Projects\TongyiFapiao\src\TongyiFapiao>dnvm list

   1.0.0-rc1-update1 coreclr x86          win

我试图更改为更新 1 的不同版本，但仍然是同样的问题。

太好了，我终于找到了有趣的东西。

第一的：

kpm和k命令分别重命名为dnu和dnx。除了这里，我找不到任何关于它的信息

您不能将 k/kre/kvm 与最新的软件包一起使用，它不了解 DNX TFM。

@jsacapdev 您需要从 Home 存储库下载 dnvm 或坚持上周五之前存在的软件包。

写于 2015 年 3 月 11 日的消息。感谢你们的大量沟通，伙计们......

所以我只需要运行命令dnx restore，然后实现我的最终目标，即从我的 DbContext 创建我的数据库。如果像我一样，您有一个多项目解决方案，您可以将网站部分与数据访问层部分 (DAL) 分开。解决方案在这里

dnx ef migrations add InitialMigration -c TongyiFapiao.DAL.TongyiFafiaoContext -p TongyiFapiao.DAL

dnx ef database update -c TongyiFapiao.DAL.TongyiFafiaoContext

但：

如果你去dnx github 页面，你可以阅读

DNX（退役）

DNX 将被淘汰，取而代之的是新的 dotnet CLI 命令行工具。看：

http://dotnet.github.io/getting-started/

http://github.com/dotnet/cli

因此，我们不再接受对此项目的任何更改。请在http://github.com/dotnet/cli上提交任何新问题。

太好了，我喜欢每 6 个月更改一次名称，这对于通过 Internet 进行理解和搜索要好得多。我保证当第四个新命令出来时我会更新这个答案。
