Postgresql 怎么初始化数据库

[yicong1352013]

尝试使用EFCore迁移命令,发现行不通,出现下面错误

Unable to create a 'DbContext' of type 'RuntimeType'. The exception 'Unable to resolve service for type 'Microsoft.EntityFrameworkCore.DbContextOptions`1[AiIncubator.Servers.Core.Data.AiIncubatorDbContext]' while attempting to activate 'AiIncubator.Servers.Core.Data.AiIncubatorDbContext'.' was thrown while attempting to create an instance. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728

程序使用EF的EnsureCreated方法来初始化数据库的，只需要配置好连接串。并保证数据库实例中不包含对应的库。直接启动程序，程序会自动创建数据库和表
