';'预期但找到“导入" - Scala 和 Spark [英] ';' expected but 'import' found - Scala and Spark

问题描述

我正在尝试使用 Spark 和 Scala，编译一个独立的应用程序.我不知道为什么会出现此错误:

I'm trying to work with Spark and Scala, compiling a standalone application. I don't know why I'm getting this error:

topicModel.scala:2: ';' expected but 'import' found.
[error] import org.apache.spark.mllib.clustering.LDA
[error] ^
[error] one error found
[error] (compile:compileIncremental) Compilation failed

这是 build.sbt 代码:

This is the build.sbt code:

name := "topicModel"

version := "1.0"

scalaVersion := "2.11.6"

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.3.1"
libraryDependencies += "org.apache.spark" %% "spark-graphx" % "1.3.1"
libraryDependencies += "org.apache.spark" %% "spark-mllib" % "1.3.1"

那些是进口:

import scala.collection.mutable
import org.apache.spark.mllib.clustering.LDA
import org.apache.spark.mllib.linalg.{Vector, Vectors}
import org.apache.spark.rdd.RDD

object Simple {
  def main(args: Array[String]) {

推荐答案

这可能是因为您的文件有旧的 Macintosh 行尾 (\r)?

This could be because your file has old Macintosh line endings (\r)?

请参阅为什么在这些导入后需要分号? 了解更多详情.
