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

Question

我正在阅读《Neo4j七周内的七个数据库》一书中的部分内容。我在第 2 天的大数据部分。我能够下载电影数据库数据集示例 ( cineasts_12k_movies_50k_actors.db)并将其移动到data/databases. 然后我注释掉dbms.active_database=graph.db并添加了这一行

dbms.active_database=movies.db 

在neo4j.conf文件中/conf folder。

根据书中的说明，我应该进入同一个文件 ( neo4j.conf) 以取消注释该行：

#dbms.allow_format_migrations=true

但是文件中不存在这样的行。并将其添加到配置文件中引发以下错误：

从在线研究来看，它似乎 ( #dbms.allow_format_migrations=true) 是一个折旧的配置选项。然后我去了A.1。https://neo4j.com/docs/operations-manual/current/reference/configuration-settings/ 上的配置设置，从我可以得出的结论看来（我自己的结论）我可以取消注释dbms.allow_upgrade代替dbms.allow_format_migrations（这是不可用/现已折旧）但我收到以下错误：

请就此提出建议，以便我可以使用示例数据集（然后继续使用其他示例数据集进行练习）。感谢您抽出宝贵时间。

注意：我运行的是 Windows 7 OS 机器；我的版本neo4j是trial neo4j-enterprise-3.4.6; 我使用cygwin终端和cmd提示来跟随这本书；我是一个初级程序员（我知道的不多）。此外，运行 Neo4j 时出现此错误：无法将版本“v0.A.9”的商店升级到当前商店版本“v0.A.8”（Neo4j 3.3.1）似乎相似但没有帮助（那里没有答案） ）。

Answer 1

我认为这个问题是由于neo4j的版本兼容性引起的。请参阅https://neo4j.com/developer/kb/store-format-versions/ 。

这个问题有两种解决方案。一种解决方案是将您使用的 Neo4j 版本降级到 2.1.0。另一种方法是手动将数据升级到 0.A.8。

祝你好运！
