Question

我正在使用Ubuntu,我已经通过这个网站的步骤安装了Griffon .即使我的安装没有错误.当我尝试使用命令运行Griffon应用程序时:

如何摆脱这个并运行我的第一个Griffon应用程序？

Answer 1

null/bin/java可能正在扩大$JAVA_HOME/bin/java.

要正确设置JAVA_HOMEUbuntu框,请添加export JAVA_HOME=/usr/lib/jvm/java-6-openjdk到您.bashrc的实际JDK路径中.readlink /etc/alternatives/javac如果您不确定JDK的安装位置,请尝试使用.
