scala - Slick Lifted 表类型错误

Question

简单地从 github example 复制示例后，我收到以下错误进入我的项目。我能够编译 github 示例项目。我觉得 sbt 一定是在把我搞得一团糟。我正在使用 sbt 0.13

[error] .scala:13: too many arguments for constructor Object: ()Object
[error]   class Suppliers(tag: Tag) extends Table[(Int, String, String, String, String,   String)](tag, "SUPPLIERS") {
[error]                  ^
[error].scala:14: object column does not take type parameters.
[error]     def id = column[Int]("SUP_ID", O.PrimaryKey) // This is the primary key column

我的 build.sbt 看起来像

导入 AssemblyKeys._

名称 := "我的项目"

版本 := "1.0"

scalaVersion := "2.10.3"

程序集设置

seq(Revolver.settings: _*)

你的进口是错误的。好像你使用了一些工具根据他们的名字自动完成它们(或者你胡乱猜测)。无论如何你导入了错误的东西。只需导入

import scala.slick.driver.H2Driver.simple._

你已经准备好了。参见 http://slick.typesafe.com/doc/2.0.0-M3/gettingstarted.html#imports
