VS Code 终端无法识别 dotnet ef

Question

在 VS Code 终端上运行以下命令时出现错误

dotnet ef -h

这是错误：

Could not execute because the specified command or file was not found.
Possible reasons for this include:
  * You misspelled a built-in dotnet command.
  * You intended to execute a .NET Core program, but dotnet-ef does not exist.
  * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.

但是在 Windows 的 cmd 上一切正常。 基于this question，我确信PATH 已在环境变量中正确定义。

Answer 1

添加 EntityFrameworkCore Tools 包。

dotnet add package Microsoft.EntityFrameworkCore.Tools
