我正在使用

MySQL DB在.Net Core 2.0中開發WEB API.我正在嘗試搭建MySQL DB.我跟隨

This link (MySQL Official Site)但是當我解除腳手架命令時我得到了錯誤我在下面提到過,如果我做錯了什么,請告訴我.

腳手架命令(在包管理器控制臺中觸發)

Scaffold-DbContext "server=localhost;port=3306;user=root;password=darshan7826;database=sakila" MySql.Data.EntityFrameworkCore -OutputDir sakila -f

執行上述命令時出錯
