我是一名本科生，我正在将 Neo4j 用于我的高级论文项目。我在 Mac 上运行它，几天前我的笔记本电脑被锁住了，我不得不不正确地关闭它。我不确定这是否导致了我当前的问题，但从那时起我就无法启动 Neo4j。我./neo4j start在控制台中运行，出现以下错误：

./neo4j start console

昨晚我删除了除graph.db之外的Neo4j文件夹并下载了最新版本，所以我从2.0.0升级到2.0.1。但是启动错误仍然存​​在。

如果有人可以提供帮助，我将不胜感激。时间快到我的最后期限了！谢谢你。

更新：

这是messages.log 文本，它很长。

The log files you've listed don't mention 2.0.1 at all, only 2.0.0.

I'd try downloading Neo4j 2.0.0 again, and seeing if that works successfully. If it does, then try cleanly shutting down, and starting the upgrade process again. It's possible that the unclean shutdown you did earlier prevents Neo4j from upgrading properly.

More practically, I'd also recommend just getting to a working state with 2.0.0, assuming you don't need a feature with 2.0.1.

你能上传 graph.db/messages.log - 这可能有某种错误消息可以解释发生了什么。

当我尝试使用比它创建的版本更旧的 Noe4j 服务器打开数据库时，我遇到了一个非常相似的问题。使用相同的版本就可以了，但发现问题并不是最明显的。

查看 graph.db/messages.log 正如 Mark 所建议的那样，console.log 中的消息对我来说提供的信息较少，只是说“检测到错误地关闭数据库，正在执行恢复..”。
