Question

当我正在使用cmd构建引擎时： pio build --verbose 我正在收到错误

我试过这个链接 No engine found. Your build might have failed. Aborting. [predictionio] ，但我的默认scala版本是2.11.8，而build.sbt是

name := "template-scala-parallel-similarproduct"

parallelExecution in Test := false
test in assembly := {}

scalaVersion := "2.11.8"
libraryDependencies ++= Seq(
  "org.apache.predictionio" %% "apache-predictionio-core" % "0.12.0-incubating" % "provided",
  "org.apache.spark"        %% "spark-mllib"              % "2.1.1" % "provided",
  "org.scalatest"           %% "scalatest"                % "3.0.4" % "test")

任何帮助将不胜感激。提前谢谢你

您是否设置了$PIO_HOME？

在运行pio build之前，您应该切换到引擎的目录（engine.json存在的位置）。

或者您可以使用pio build -v engine.json。

在PIO中构建MySimilarProduct引擎
