Question

我试着用predictionIO来使用通用推荐。我使用的是模板: template-scala-parallel-universal-recommendation.我已经导入了文件，在构建引擎时，我得到了一个错误：

[INFO] [Engine$] [warn]     module not found: 
[INFO] [Engine$] [warn] ==== local: tried
[INFO] [Engine$] [warn]   /home/neron/.ivy2/local/io.prediction/core_2.10/0.12.0-incubating/ivys/ivy.xml

和

在我的.ivy2文件夹中，我有如下文件夹：

/home/name/.ivy2/local/org.apache.predictionio/apache-predictionio-core_2.10/0.10.0-incubating/ivys/ivy.xml

而不是io.prediction/core/....

我尝试用我拥有的路径更改engine.sbt文件，但仍然得到与我提供的路径相同的错误。

这是因为我做了什么其他的错误吗？
