c# - 找不到命令“dotnet ef”

问题描述

我在Arch Linux / Visual Studio Code 上使用 .NET Core 2.0 并试图让EF工具工作，但我不断收到错误消息：

找不到命令 dotnet ef

我只是到处寻找，但没有一个建议奏效。

运行“dotnet ef”的结果：

[wasiim@wasiim-PC WebApiServerApp]$ dotnet ef --help
Cannot find command 'dotnet ef', please run the following command to install

dotnet tool install --global dotnet-ef
[wasiim@wasiim-PC WebApiServerApp]$ dotnet tool list -g
Package Id            Version      Commands
---------------------------------------------------
dotnet-dev-certs      2.2.0        dotnet-dev-certs
dotnet-ef             2.2.3        dotnet-ef
[wasiim@wasiim-PC WebApiServerApp]$

如果有帮助，这是“dotnet --info”结果：

[wasiim@wasiim-PC WebApiServerApp]$ dotnet --info

解决方案

在我的情况下，里面不存在工具文件夹，%USERPROFILE%\.dotnet\所以我必须运行命令dotnet tool install --global dotnet-ef来安装 dotnet ef。然后我就可以运行 dotnet ef ...

这是上述安装命令的结果：
