下载的eclipse-SDK-2.1-linux-gtk.tar.gz
解压后到目录里执行
./eclipse
出错:
A Java Runtime Environment (JRE) or Java Development Kit (JDK)
must be available in order to run Eclipse. No Java virtual machine
was found after searching the following locations:
/home/ling/download/eclipse/./jre/bin/java
'java' in your current PATH
这个环境变量怎么设置?
