提问by VB_
I entered Scala courses on Coursera and used to write Scala projects in Eclipse Indigo. All worked well. But now I gonna to convert to my favorite IDE - Intellij IDEA.
我在 Coursera 上学习了 Scala 课程，并且曾经用Eclipse Indigo. 一切都很好。但现在我要转换为我最喜欢的 IDE - Intellij IDEA。
But I can't configure it for Scala usage.
但我无法为 Scala 使用配置它。
What I've already done:
我已经做了什么：
- Install Scala, set system
SCALA_HOMEvariable - Install SBT
- Install Scala plugin on Intellij IDEA
- 安装 Scala，设置系统
SCALA_HOME变量 - 安装 SBT
- 在 Intellij IDEA 上安装 Scala 插件
What a problem:
有什么问题：
When I import coursera assignments, Intellij doesn't see some classes like
List,Arrayetc. For example, when I try to import it viaAlt+Enterkey it propose mejava.jang.reflect.Array,java.sql.Array,com.sun.xml....Array. So I can't import Scala Array withtailandheadmethods.When I try:
New Project->Scala Modulethe are to problems:a) When I choose
Set Scala Homeit complains that there are missing filesb) When I choose
Existent Librarythere is nothing to choose inCompiler/Standartfields.
当我导入 coursera 作业时，Intellij 看不到诸如
List、Array等的某些类。例如，当我尝试通过Alt+Enter密钥导入它时，它会建议我java.jang.reflect.Array,java.sql.Array,com.sun.xml....Array。所以我不能用tail和head方法导入 Scala 数组。当我尝试：
New Project->Scala Module问题：a) 当我选择
Set Scala Home它时，它抱怨缺少文件b) 当我选择时
Existent Library，在Compiler/Standart字段中没有任何选择。

Is the directory you specified the right one? It should have bin, doc, etc. in it. If so, try entering the following by hand:
您指定的目录是否正确？它应该有 bin、doc 等。如果是这样，请尝试手动输入以下内容：
For compiler library, scala-compiler
对于编译器库， scala-compiler
For standard library, scala-library
对于标准库， scala-library
IDEA found these for me automatically, but perhaps something went wrong for you.
IDEA 会自动为我找到这些，但也许您出了点问题。

It can be a problem with caches, try File -> Invalidate Caches
缓存可能有问题，请尝试 File -> Invalidate Caches
回答by Dirk bachmann
Make sure to manually add the scala-libraryas a dependency to your module.
This is not done automatically when adding the Scala facet to an existing module.
确保将 手动添加scala-library为模块的依赖项。将 Scala 方面添加到现有模块时，这不会自动完成。
