问题
I am trying to export my db as a graphml file via the apoc.export.graphml procedure in Neo4j 3.1 + 3.1.0.3:
call apoc.export.graphml.all("test",{})
I get this error message:
Failed to invoke procedure
apoc.export.graphml.all: Caused by: java.lang.RuntimeException: Import from files not enabled, please set apoc.import.file.enabled=true in your neo4j.conf
I have edited my neo4j.conf file to add
apoc.import.file.enabled=true
at the end of the document but I'm still getting the same error message.
What am I doing wrong?
Thanks for your help.
回答1:
I had the same problem and did not find any from anywhere. I just managed to resolved this issue. Hopefully, this solves yours as well.
Environment: MacOs, Neo4j 3.1.2 CE
1) Change your .neo4j.conf (mine is under my ~/Documents/Neo4j/). You can easily edit by pressing [Options...] button. I commented the import directory comment out as well, just in case.
#dbms.directories.import=import
apoc.import.file.enabled=true
2) I originally have the apoc-3.1.2.5.jar under ~/Documents/Neo4j/default.graphdb/plugins/ directory which worked except reading xml from the local disk. So, I put the jar under my app directory, /Applications/Neo4j.app/Contents/Resources/app/plugins
The "Neo4j.app" is my symbolic link. You probably will see the app directory as "Neo4j Community Edition 3.1.2.app"
3) Do Not restart by pressing [Stop] and [Start], make sure you quit the Neo4j and relaunch. Stop and Start seems to reload config but it does not seem to load jar from plugins.
4) How to check:
call apoc.config.list
You should see:
apoc.import.file.enabled true

I originally added
apoc.import.file.enabled=true
to the end of the neo4j.conf file and "HTTP logging configuration" section.
I moved the comment to the "Server configuration" section and now it works.
