Exception in thread “main“ java.lang.NoClassDefFoundError: javax/script/Compilable

scala的交互模式启动时出现这个问题:

完整报错如下:

$scala
Shell 传递参数实例！
执行的文件名：/home/appleyuchi/scripts/scala/scala.sh

解决方案:

/home/appleyuchi/bigdata/scala-2.11.8/bin/scala

/home/appleyuchi/bigdata/scala-2.11.8/bin/scalac

各自在文件中加入一句:

export JAVA_HOME=~/Java/jdk1.8.0_131

这个解决方案的原理是用局部JAVA_HOME变量覆盖~/.bashrc中的JAVA_HOME变量。

原因:

与JDK9不兼容，使用JDK8即可.
