绝对的 Scala 初学者。我在 macOS X 中安装了 scala 2.12.1。

我正在尝试从此处computer-database设置示例Play-Slick 示例

一旦我cd进入计算机数据库，我就跑了sbt run，它会导致这个错误：

error: not found: value PlayKeys "PlayKeys.playOmnidoc := false"

这些是build.sbt文件夹根目录的默认内容：

name := "computer-database-sample"
PlayKeys.playOmnidoc := false

在 PlayKeys 调用之前，我尝试添加以下行以build.sbt显式导入 play-slick：

libraryDependencies ++= Seq(
    "com.typesafe.slick" %% "slick" % "2.0.0",
    "com.typesafe.play" %% "play-slick" % "0.6.0.1",
    "com.typesafe.slick" %% "slick-extensions" % "3.1.0"
)

但我仍然遇到同样的错误。

我错过了什么吗？这是应该如何设置scala项目的吗？

停止你正在做的任何修改，恢复它们（你需要从 repo 获得干净的版本）。

执行以下操作（不是最快的根，但可以让您随时探索其他方面的内容）：

1）转到回购根目录。

2）类型：sbt- 我它不起作用，sbt先安装

3) 在第 2 点成功之后，您应该会看到以下内容：

[pdolega@maracuja play-slick]$ sbt

4) 类型：projects. 您将看到所有sbt子项目：

> projects
[info] In file:/home/pdolega/projects/slick/play-slick/
[info]     basic-sample
[info]     computer-database-sample
[info]     docs

[info]     play-slick
[info]     play-slick-evolutions
[info]   * play-slick-root
[info]     samples
>

4) 键入project computer-database-sample<- 这将使您想要的子项目处于活动状态。

> project computer-database-sample
[info] Set current project to computer-database-sample (in build file:/home/pdolega/projects/slick/play-slick/)
[computer-database-sample] $

5) 现在您可以进行安装，test这将运行编译和之后的所有测试。或者您可以键入run以启动此示例 Play 应用程序。

[computer-database-sample] $ run
[warn] Credentials file /home/pdolega/.bintray/.credentials does not exist
