推荐答案

检查脚本编译node-java我看到的设置为bootclasspath那里：
-bootclasspath /opt/jdk/jre/lib/rt.jar

Checking the script to compile node-java I see the setting for bootclasspath there: -bootclasspath /opt/jdk/jre/lib/rt.jar

你有这个jar文件 /opt/jdk/jre/lib/rt.jar ？如果没有，那么您可能需要调整脚本以指向您的JRE位置。

Do you have this jar file /opt/jdk/jre/lib/rt.jar? If not, then you may want to adjust the script to point to your JRE location.
