使用offline graph.db启动NEO4j社区实例时出错

我的图有大约2700万个关系和1500万个节点。 当我尝试使用使用neo4j导入工具创建的graph.db数据库启动neo4j实例时，出现以下错误：

sudo service neo4j status

尝试在

neo4j.conf

中取消注释这一行，因为我认为neo4j导入工具尚未升级到支持3.2.x版本

# Enable this to be able to upgrade a store from an older version.
#dbms.allow_format_migration=true

您使用的是哪个版本？@TomažBrataničI使用的是Neo4j 3.2.0I已经取消了这一行的注释，但是，Neo4j实例启动了一次，但没有再次启动。您只需要第一次使用它。。。然后你可以回复
