K ef 命令给出“k : System.Exception: Unable to locate project.json”答案

【问题标题】：K ef command gives "k : System.Exception: Unable to locate project.json "K ef 命令给出“k : System.Exception: Unable to locate project.json”
【发布时间】：2015-06-10 04:03:42
【问题描述】：

当我尝试添加迁移时，“k”给了我以下错误：

k : System.Exception: Unable to locate project.json
At line:1 char:1
+ k web
+ ~~~~~
+ CategoryInfo          : NotSpecified: (System.Exceptio...te project.json:String) [], RemoteException
+ FullyQualifiedErrorId : NativeCommandError

bij Microsoft.Framework.Runtime.DefaultHost.Initialize(DefaultHostOptions options, IServiceProvider hostServices)
bij Microsoft.Framework.Runtime.DefaultHost..ctor(DefaultHostOptions options, IService
Provider hostServices)
bij Microsoft.Framework.ApplicationHost.Program.Main(String[] args)

这是我的 global.json：

{
"projects": [ "src", "FoodDelivery" ],
"sdk": {
    "version": "1.0.0-beta4"
    }
}

我有以下目录结构

FoodPick
FoodPick/src
FoodPick/src/FoodDelivery
FoodPick/src/FoodDelivery/project.json
FoodPick/src/FoodShare
FoodPick/artifacts
FoodPick/global.json

我想从 FoodDelivery 项目执行 k ef 迁移添加，其中包含一个 project.json

这是 project.json 的内容。

或者，我通过命令控制台 (cmd.exe) 执行命令。以下是我收到的错误。

这是我在运行 kpm restore 时收到的错误

PM> kpm restore

现在我读到当前命令，而不是“k ef migration add the_migration_name”，是“dnvm ef migration add the_migration_name”

dnvm 已经安装，但是命令不起作用（如果这是要走的路）...

我想知道可能出了什么问题，并帮助我进一步寻求：p

【问题讨论】：

问题是它无法find文件。换句话说，文件不在它正在寻找的地方。（提示：不太可能在您的源代码树中查找文件......因为您的源代码树不太可能在运行时存在。）
现在可能很愚蠢。但我使用包管理器控制台并选择 src\FoodDelivery 作为默认项目。然后我使用“k ef”，它找不到文件。我在某处读到 global.json 中的错误可能是导致此问题的原因（这就是我添加它的原因）。但我不明白为什么它找不到文件......它就在那里：p。该命令不是在运行时与项目一起执行，而是在开发期间执行。
k-命令已重命名：github.com/aspnet/Announcements/issues/4

标签： asp.net-mvc asp.net-core

【解决方案1】：

自 beta4 以来，已经进行了一些重命名：

k -> dnx
kpm -> dnu
kvm -> dnvm

如果您仍有一些旧应用程序，请编辑PATH 环境变量并删除与.k 相关的任何内容

【讨论】：

【解决方案2】：

正确使用的命令是：

dnx . ef migration add initial //NEW & working through cmd.exe in the projects directory 

k ef migration add //OLD -- DO NOT USE -- Doesn't work anymore
