与安装JRuby时的某些内容相关的错误确实很紧密。 在使用RVM安装JRuby时，它有一个编译需要的依赖项，我相信它不是那么好。我不太记得哪个依赖项。它接缝属于JVM和-Xcext。
~$ scala
Unrecognized option: -Xcext.enabled=true
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
此处没有Google搜索结果。
我已尝试使用http://www.scala-lang.org版本2.11.1中的最新版本并收到了此错误。
java version "1.7.0_55"
OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1)
OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)
尝试通过RVM重新安装JRuby并没有要求构建任何依赖项。因此，我必须在线查找-Xcext案例并弄清楚。 ......我似乎无法找到有问题的东西。
~$ irb
Unrecognized option: -Xcext.enabled=true
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
它会影响RubyMine。我真的想知道这个问题嵌入了哪里，因为它引起了一些令人头疼的问题！

$JAVA_HOME was empty, setting up JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/jre, if it fails try setting JAVA_HOME to something sane and try again.

听起来您在其中一个JVM的选项环境变量中有-Xcext.enabled=true，例如JAVA_OPTS，_JAVA_OPTIONS或JAVA_TOOL_OPTIONS。我假设在某些时候它应该被添加到特定于JRuby的环境变量中，但是意外地被放入其中一个JVM中。
