我怀疑您缺少脚手架所需的组件?我还假设您正在尝试对现有数据库进行逆向工程?

I suspect you are missing the assemblies that are necessary for scaffolding? I also assume you are trying to reverse engineer an existing db?

示例Scaffold-DbContext "Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

如果它失败，例如我找不到它，可能是pmc问题，请尝试关闭VS再试一次.之后，可能是缺少程序集的配置.

if it fails like i can't find it might be a pmc issue, try closing down VS try again. After that its probably a configuration with missing assemblies.
