ASP.NET 5: kpm 找不到 EntityFramework.Sqlite 和 Microsoft.Data.Sqlite 包
ASP.NET 5: kpm can't locate EntityFramework.Sqlite and Microsoft.Data.Sqlite packages
我正在尝试在 ASP.NET 5 网站中使用 SQLite，但我在使用 EntityFramework.Sqlite 和 Microsoft.Data.Sqlite 包时遇到了问题。
kpm restore 命令给我：

和 kpm build 也给我：

然而，当我从 Visual studio 构建时，它工作得很好，从我的 .dnx\packages 目录中获取包：

我还升级了我的 KVM 和 DNVM，这里是安装的所有 .NET 版本：

我试过更换不同版本的update 1，但还是一样的问题。
太好了，我终于找到了有趣的东西。
第一个：
kpm 和 k 命令分别重命名为 dnu 和 dnx 。
除了 here
，我找不到任何关于它的信息
You can't use k/kre/kvm with the newest packages, it doesn't understand the DNX TFMs.
@jsacapdev You need to download the dnvm from the Home repository or stick to packages that existed before last friday.
消息写于 2015 年 3 月 11 日。感谢您对此的大量交流...
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。解决方案是here
dnx ef migrations add InitialMigration -c TongyiFapiao.DAL.TongyiFafiaoContext -p TongyiFapiao.DAL
dnx ef database update -c TongyiFapiao.DAL.TongyiFafiaoContext
但是：
如果你去dnx github page你可以阅读
DNX (retired)
The DNX is being retired in favor of the new dotnet CLI command line tools. See:
http://dotnet.github.io/getting-started/
As a result, we're not accepting anymore changes to this project. Please file any new issues on http://github.com/dotnet/cli.
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。我保证会在第 4 个新命令发布时更新此答案。
