“错误：JAVA_HOME未正确定义”。在建筑Jikes rvm

问题描述：

当我在Unbuntu上构建Jikes RVM时，我收到了这个错误。任何想法？

When I built the Jikes RVM on Unbuntu, I got this error. Any idea?

操作系统：

Linux ubuntu 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 06:07:29 UTC 2010 i686 GNU/Linux

环境变量：
PATH

Environmental Variables: PATH

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/java-6-sun-1.6.0.22/bin

JAVA_HOME

/usr/lib/jvm/java-6-sun-1.6.0.22

$ b c $ c>目录，它的工作原理。
无论我如何更改环境变量，错误仍然抱怨我们无法执行/opt/jdk1.6.0/bin/java。似乎我没有修改正确的位置。

I checked the java in the JAVA_HOME/bin directory, it works. No matter how I change the environmental variables, the error kept complaining "We cannot execute /opt/jdk1.6.0/bin/java". It seems that I didn't modify the right "position".

任何线索？

谢谢！ / p>

Thanks!

答

运行此命令：

find . -exec grep "jdk1.6.0" {} \;

找出哪个文件正在将JAVA_HOME设置为该路径。

To find out which file is setting JAVA_HOME to that path.
