找不到可執行文件匹配命令「dotnet-ef」（軟件包管理器）

我正在製作.Net Core上的教程，我無法使用軟件包管理器控制檯。找不到可執行文件匹配命令「dotnet-ef」（軟件包管理器）

我對這個Link

使本教程中，當我在包管理器控制檯寫插件遷移或更新DATEBASE（例）：

DOTNET EF miggrations添加耶尼

事實證明這錯誤：

dotnet : No executable found matching command "dotnet-ef" 
At line:1 char:1 
+ dotnet ef miggrations add Yeni 
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 
    + CategoryInfo   : NotSpecified: (No executable f...and "dotnet-ef":String) [], RemoteException 
    + FullyQualifiedErrorId : NativeCommandError

我可以更新我的數據庫，還是可以在包管理器控制檯上添加新的遷移？如何？

這裏是我的projects.json

添加'project.json'文件的內容，請 – Dmitry

這不要緊，我tryed新的項目，但它不工作...我會加 –

嗯，你有很多EntityFrameworkCore包。 ..我少了。嘗試刪除除3之外的所有內容（2個依賴關係和一個工具） - 請參閱http://stackoverflow.com/documentation/entity-framework-core/3796/introduction-to-entity-framework-core/13132/adding-packages -項目。我用我自己的項目作爲源。如果這不會幫助 - 創建小項目，並把github/bitbucket/... – Dmitry

包管理器控制檯不支持「全局命令」呢。它只能在項目文件夾（包含project.json的文件夾）中理解「dotnet-ef」。

所以，你可以嘗試以下操作之一：

嘗試改變PMC的當前目錄到 project.json所在的文件夾。（默認情況下，它指向解決方案的根目錄文件夾，而不是項目。）
使用powershell運行該命令。

非常感謝你這是我的回答:) –

我得到的消息'dotnet：沒有可執行文件找到匹配命令「dotnet-ef」'無關緊要什麼。 –

您是否安裝了dotnet cli？請嘗試遵循https://docs.asp.net/en/latest/tutorials/first-mvc-app/adding-model.html以確保您具備所有先決條件。 – Jack
