我使用的是neo4j-enterprise-2.2.4

请帮帮我！谢谢大家！

这是我的错误信息：

我对Neo4J一无所知，但似乎你的问题与版本不匹配有关。

您的日志显示您正在访问位于neo4j-enterprise-2.2.4单元中的d:个实例。但是您的pom.xml已为2.1.5版本配置了依赖项。

稍后，您的日志会抱怨NodeStore：

中存在不匹配

引起：org.neo4j.kernel.impl.storemigration.StoreUpgrader $ UnexpectedUpgradingStoreVersionException：'neostore.nodestore.db'有一个我们无法升级的商店版本号。 预计'v0.A.1'，但文件版本为'NodeStore v0.A.5'

我在github here上发现了类似的错误（虽然那个错误相反，依赖关系比nodestore 更新），但它是通过匹配版本（或升级nodesotre但不是你的情况），所以我认为你必须将你的依赖关系升级到2.2.4。

让它有所帮助。
