ASP.NET dnx ef命令System.TypeInitializationException

我有一个asp.NETMVC6项目

我在提示窗口中运行此命令。首先使用代码，我尝试创建数据库。我不知道我的错误在哪里，或者我错过了图书馆

1-dnvm安装1.0.0-beta8 2-dnvm使用1.0.0-beta8 3-dnu恢复 4-dnx ef数据库更新（如果运行dnx ef--help或dnx ef，则相同）

您正在将

rc1

包与

beta8

dnx一起使用。升级到dnx

rc1 final

，它应该可以工作。

我有两个笔记本。一个没有问题，另一个有问题，所以我写问题。你的回答是正确的。我不知道为什么在一本笔记本上没有抱怨版本，但你是对的。谢谢。我有两本笔记本。一个没有问题，另一个有问题，所以我写问题。你的回答是正确的。我不知道为什么在一本笔记本上没有抱怨版本，但你是对的。非常感谢。
