Question

我从网站上下载了neo4j.zip并将其解压缩。我下载并安装了jdk 7，我有两个文件夹：

C:\Program Files\Java\jdk1.7.0_75

和

C:\Program Files\Java\jre7

我点击了New并创建了一个名为JAVA_HOME的变量，其值为

C:\Program Files\Java\jdk1.7.0_75

我添加了

org.neo4j.server.startup_timeout=0

由于超时错误而导致我的neo4j-server.properties文件我已将neo4j-server.properties文件中的端口号从7474更改为80和8085，这是我的neo4j-server.properties现在：

但是再次当我通过双击它运行Neo4j.bat时，cmd窗口将打开并且java窗口将打开并在几秒钟后关闭并且cmd窗口将在它之后关闭并且

不可用。

这是我的错误来自

我该怎么办才能运行Neo4j并使用它？我有Windows 7 x86 提前谢谢。

Answer 1

我今天遇到了同样的错误。在我的情况下，这是因为数据库目录中的文件已损坏（我解压缩了第一次尝试失败的现有图表）。在我正确地解压缩现有的图形数据库 - 并且数据库文件很好 - 它工作了。因此，您的数据库目录也可能已损坏。

neo4j不断出错并且没有运行，你能帮我解决它的错误吗？
