java - Neo4j Java 7 终端问题

Question

我在启动 Neo4j 实例 (2.0.0 M03) 时遇到问题。我已经安装了 java 7，如下面的代码块所示，但是当尝试启动 neo4j 时，它显然无法识别这一点，给出错误并且无法启动。终端输出如下。关于如何解决这个问题或到底出了什么问题有什么想法吗？非常感谢。

Answer 1

问题是 JAVA_HOME 未设置为正确的 JVM。要确定实例的安装位置，您可以在终端中输入以下内容:

/usr/libexec/java_home -v 1.7

这应该返回位置，在我的例子中:/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/

要设置 JAVA_HOME，只需导出指向如下位置(进入控制台):

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/
