Question

我试图在ASP.NET 5网站中使用SQLite，但我遇到了EntityFramework.Sqlite和Microsoft.Data.Sqlite软件包的问题。 kpm restore命令给了我：

和kpm build也给了我：

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

然而，当我从Visual Studio构建时，从我的.dnx \ packages目录中获取包时，它工作得非常好：

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，它似乎有效：

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，但它们都没有工作。我还升级了我的KVM和DNVM，这里安装了所有.NET版本：

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

   1.0.0-rc1-update1 coreclr x64          win
   1.0.0-rc1-update1 coreclr x86          win

我尝试更改为更新1的不同版本，但仍然存在同样的问题。

Answer 1

Soooo我终于找到了有趣的东西。

<强> FIRST：

kpm和k命令分别重命名为dnu和dnx 。除here

外，我无法找到有关它的任何信息

你不能在最新的软件包中使用k / kre / kvm，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。

2015年3月11日写的留言。感谢您就此与您进行了大量沟通......

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，你有一个多项目解决方案，你可以从数据访问层部分（DAL）拆分网站部分。解决方案是here

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

dnx ef database update -c TongyiFapiao.DAL.TongyiFafiaoContext

<强> BUT：

如果你转到dnx github page，你可以阅读

DNX（退休）

DNX正在退役，转而使用新的dotnet CLI命令行工具。参见：

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

http://github.com/dotnet/cli

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

太棒了，我喜欢每隔6个月更名一次，这对于理解和搜索互联网来说要好得多。我保证当第4个新命令出来时我会更新这个答案。
