Question

在尝试导入从维基百科数据生成的csv时，我收到以下错误：

rolf@shogun:~$ neo4j-import --into wiki.db --id-type string --bad-tolerance 12998873 --skip-bad-relationships true --multiline-fields true --nodes:Page entities2.csv --relationships:LINK links2.csv --stacktrace true --skip-duplicate-nodes true
Importing the contents of these files into wiki.db:
Nodes:
  :Page
  /home/rolf/entities2.csv
Relationships:
  :LINK
  /home/rolf/links2.csv

我已经尝试过滤＆amp;和/但仍然是相同的错误（在类似的问题中提到）。

关系csv（links2.csv）主要包含在entities2.csv中不存在的引用，因为它只是数据的一小部分。

我正在使用neo4j 2.2.5

这是已在代码库中修复的已知问题，请参阅https://github.com/neo4j/neo4j/commit/45520e329403e166743b0027e75f2f658019ceae。您可以等待2.2分支或2.3分支中的下一个版本（另一个里程碑或RC）。或者，抓住源代码并自己构建快照。

neo4j-import：必须按递增节点ID的顺序提供NodeLabelUpdates
