neo4j drwho 数据集升级到 3.0 不工作
neo4j drwho dataset upgrade to 3.0 not working
我正在尝试在我的 Mac OSX 中使用来自 http://neo4j.com/developer/example-data/ 的 "Jim Webber’s Doctor Who Data Set" 和 Neo4j 3.0.1 社区。
我正在执行这些步骤（文档是 here）：
- 将压缩数据文件下载到导入目录（为了方便），并将其重命名为
graph.db。
- 在
$NEO4J_HOME/conf/neo4j.conf 中设置dbms.allow_format_migration=true
- 使用
$NEO4J_HOME/bin/neo4j-admin import --mode=database --database=graph.db --from=$NEO4J_HOME/import/graph.db/ 导入数据
- 启动neo4j服务器
neo4j 控制台无法启动，出现以下错误消息：

有人知道如何解决吗？有没有人设法使用文档中的数据集？
谢谢！
Neo4j 3.0 允许从任何完全关闭的 Neo4j 2.x 数据集直接升级。但是，您所指的 DrWho 数据集来自 Neo4j 1.9（或更早版本）的旧时代。因此，您需要一个两步升级过程：
- 下载 Neo4j 2.3.3（或任何新的 2.x 版本）
- 将 drwho.zip 解压为
data/graph.db
- 在
conf/neo4j.properties 中设置allow_store_upgrade=true
- 正常启动和停止数据库
- 解压 neo4j 3.0.x
- 将
data/graph.db 从 Neo4j 2.x 复制到 data/databases/graph.db
- 在
conf/neo4j.conf 中设置dbms.allow_format_migration=true
- 启动 Neo4j 3。0.x
