Neo4j不'；我不能再开始了

我的Neo4j数据库不再响应，所以我不得不终止进程，之后它就不再启动了。有人能帮我修一下吗？以下是错误日志：

看起来您仍然有一些neo4j进程在后台运行。看看你是否能找到它，然后杀死它。

今天早上我遇到了同样的错误消息。这是对我有用的东西。我创建了一个新的数据库文件夹，将启动屏幕指向新的位置-启动成功。然后我关闭了这个新实例，并重新指向一个现有的（失败的）db位置，然后按照正常方式启动。我希望它能有所帮助。

我删除了现有的图表并创建了一个新的。这一次，我确保选择了与最新插件（APOC等）库版本相匹配的正确版本的Graph（在我的例子中是3.5.0），并且我的数据库成功启动
