我使用nuget将这些添加到我的项目中：微软.实体框架核心.设计版本7.0.1柚子.实体框架核心.MySQL版本6.0.2
脚手架：dotnet ef dbcontext scaffold名称=罗斯文DB Pomelo.EntityFrameworkCore.MySql --输出目录模型--上下文目录数据--命名空间罗斯文.模型--上下文命名空间罗斯文.数据--上下文罗斯文上下文-f --禁止配置
最后出现以下错误

Scaffolding fails with the following output:
C:\Northwind.MySQL\Northwind.MySQL\Northwind.MySQL.csproj : error NU1107: Version conflict detected for Microsoft.EntityFrameworkCore.Relational. Install/reference Microsoft.EntityFrameworkCore.Relational 7.0.1 directly to project Northwind.MySQL to resolve this issue.

Build FAILED.

我尝试在依赖项中添加对Microsoft.EntityFrameworkCore.Relational dll的引用，但得到了相同的错误。
我尝试了不同版本的依赖项，我已经无计可施了。有没有人用pomelo库成功地做了这种搭建？
