无法将版本“ v0.A.3”的商店升级到当前商店版本“ v0.A.9”（Neo4j 3.4.6）-相关的数据集示例

时间：2018-08-24 03:58:46

标签： neo4j

我正在研究《七个星期的七个数据库》一书的Neo4j部分。我现在是第2天的“大数据”部分。我能够将“电影数据库”数据集示例（cineasts_12k_movies_50k_actors.db）下载并移动到data/databases。然后，我将dbms.active_database=graph.db注释掉并添加行

dbms.active_database=movies.db

在neo4j.conf的{​​{1}}文件中。

根据书中的说明，我应该进入同一文件（/conf folder）中以取消注释：

neo4j.conf

，但是该行在文件中不存在。并将其添加到配置文件中引发以下错误：

#dbms.allow_format_migrations=true

从在线研究来看，（C:\Users\w3s\Desktop\NEO4J_HOME\neo4j-enterprise-3.4.6-windows\neo4j-enterprise- 3.4.6\bin>neo4j console 2018-08-24 03:37:28.996+0000 WARN Unknown config option: dbms.allow_format_migr ations 2018-08-24 03:37:29.076+0000 INFO ======== Neo4j 3.4.6 ======== 2018-08-24 03:37:29.170+0000 INFO Starting... 2018-08-24 03:37:33.672+0000 INFO Initiating metrics... 2018-08-24 03:37:34.180+0000 ERROR Failed to start Neo4j: Starting Neo4j failed: Component 'org.neo4j.server.database.LifecycleManagingDatabase@6db66836' was su ccessfully initialized, but failed to start.

然后，我注释掉了'dbms.allow_upgrade'行并再次运行neo4j控制台以在cmd上启动服务器，并出现以下错误：

请就此提出建议，以便我可以使用示例数据集（然后继续进行其他示例数据集的练习）。 多谢您的宝贵时间。

1 个答案:

答案 0 :(得分：0)

我认为此问题是由neo4j的版本兼容性引起的。 参见https://neo4j.com/developer/kb/store-format-versions/。

此问题有两种解决方案。一种解决方案是将以前使用的neo4j版本降级为2.1.0。另一个是手动将数据升级到0.A.8。

祝你好运！
