我已经安装了 JetBrains Scala 插件，然后打开了一个包含 SBT 构建的目录并重置/重新启动了我的缓存(文件 -> 使缓存无效/重新启动).但它仍然不起作用！有谁知道为什么?
I already installed the JetBrains Scala plugin, then opened a directory with an SBT build and reset/restarted my cache (File -> Invalidate Caches / Restart). But it still doesn't work! Does anyone know why?
推荐答案
您的 scalatest 依赖配置错误.您希望为 Scala 2.12 发布最新的 2.6 版.没有这样的组合，因此您的构建失败.如果您查看 Scala 2.12 可用的 scalatest 版本，这里是 链接.如您所见，它只有 3.0.0 版本.因此，您有 3 个选项(这些是您需要在 build.sbt 文件中进行的更改):
Your scalatest dependency is misconfigured. You want scalatest version 2.6 published for Scala 2.12. There is no such combination, hence your build fails. If you have a look at which version of scalatest is available for Scala 2.12, here's the link. As you can see, it's only version 3.0.0. So, you have 3 options (those are changes in your build.sbt file you need to make):
- 将您的 scalatest 版本更新为 3.0.0:
libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.0" % Test - 将您的 Scala 版本降级到 2.11:
scalaVersion := "2.11.8" - 以上两种
我会说现在使用 Scala 2.12 还为时过早，因为它在几天前才发布，而且还没有发布所有依赖项.Scala 主要版本(2.11 与 2.12 是 Scala 的主要版本升级)不是二进制兼容的，因此您不能在使用另一个 Scala 版本的项目中使用使用另一个版本编译的库.
I'd say it's a bit too early to use Scala 2.12, since it was only released a couple of days ago, and not all of the dependencies are published for it yet. Scala major versions (2.11 vs 2.12 is a major version upgrade for Scala) are not binary compatible, so you can't use a library compiled with one Scala version in a project that uses the other.
同时，我会选择 scalatest 3.0.0 版本，因为它是稳定版本.所以总而言之，我现在会选择选项 3，尽管选项 1 和 2 会以不同的方式解决这个特定问题.
At the same time, I'd go with scalatest 3.0.0 version, since it's the stable one. So all in all, I'd go for option 3 at the moment, even though options 1 and 2 will fix this particular problem, in different ways.
