错误：找不到或加载主类org.apache.mahout.driver

Question

我正在尝试在本地计算机上安装独立Mahout，可以在其中运行spark-itemsimilarity命令。我收到以下错误消息：

$ ./mahout
Adding lib/ to CLASSPATH
MAHOUT_LOCAL is set, running locally 
Error: Could not find or load main class org.apache.mahout.driver.MahoutDriver

类似地用于火花项相似性

$ ./mahout spark-itemsimilarity
Adding lib/ to CLASSPATH
/Users/james/mahout/examples/target/classes:
...
...
:/Users/james/mahout/bin/mahout-spark-class.sh
Error: Could not find or load main class org.apache.mahout.drivers.ItemSimilarityDriver

这是我尝试过的-

1. 下载了Mahout 0.14，Spark和Hadoop
2. 使用mvn -DskipTests -X全新安装从源代码构建Mahout
3. 通过mvn测试进行了测试
4. bashrc_profile中的环境变量

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home
export MAHOUT_HOME=/Users/james/mahout
export MAHOUT_LOCAL=true
export SPARK_HOME=/Users/james/spark
export HADOOP_HOME=/Users/james/hadoop
export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin



export PATH=$PATH$:MAHOUT_HOME/bin:$:MAHOUT_HOME/lib:$HADOOP_HOME/bin:$SPARK_HOME/bin:$JAVA_HOME/bin

1. 启动Spark master（独立）
