尝试运行迁移步骤时收到错误

这是我的dnvm列表：

我正在浏览这个，但到目前为止，这个新的ASP.NET似乎非常错误。 http://docs.asp.net/en/latest/tutorials/your-first-aspnet-application.html

更新

dnu构建输出

Answer 1

将我的评论答案移到实际答案（并稍微清理一下） - 看起来版本错了。默认显示为clr，即使活动版本是coreclr。在这种情况下，我建议明确告诉dnvm / dnu / dnx将活动运行时与活动arch一起用于各种构建命令，例如：dnvm exec 1.0.0-rc1-update1 -r coreclr dnu build并且还可能更新-arch标志以使用x86而不是x64。

dnx ef migrations add Initial dnx：System.ArgumentNullException：Value不能为null
