I'm having issues starting my neo4j instance (2.0.0 M03). I have java 7 installed as indicated in the code block below but when trying to start neo4j it apparently does not recognize this, gives and error and does not start. The terminal output is below. Any ideas on how to fix this or what exactly is going wrong? Thanks a lot.

推荐答案

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

The problem was JAVA_HOME was not set to the correct JVM. To determine where you have your instance installed you can enter the following into terminal:

/usr/libexec/java_home -v 1.7

在我的情况下，这应该返回位置:/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/

This should return the location, in my case: /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/

要设置JAVA_HOME，只需导出指向如下所示的位置(进入控制台)即可:

To set JAVA_HOME just export pointing towards the location like below (enter into the console):

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