missing dependency error with neo4j-core 3.0.0.alpha.2 #36

Closed arikan closed 10 years ago

arikan commented 10 years ago

after installing the alpha version

gem install neo4j-core -v 3.0.0.alpha.2

tried in irb and got the following error:

jruby-1.7.4 :001 > require 'neo4j-core'

NameError: cannot link Java class org.neo4j.graphdb.DynamicLabel, probable missing dependency: org/neo4j/graphdb/DynamicLabel : Unsupported major.minor version 51.0
from org/jruby/javasupport/JavaClass.java:1242:in `for_name'

What would be wrong here, also here is my gem list:

Are you sure you are using the right version. Try to remove all old neo4j-core gems.

andreasronge commented 10 years ago

It is really strange. Have you solve the problem ? I can't reproduce this problem. Are you on windows,mac or linux ? I did a new release alpha.3 but it I think it will not solve your problem.

Strange, I'm also on mac but using java version "1.7.0_10" check this: http://stackoverflow.com/questions/10382929/unsupported-major-minor-version-51-0 Btw, made a very basic rails app with v3.0 of neo4j - https://github.com/andreasronge/neo4j/tree/3.0/example/blog

arikan commented 10 years ago

Installed java version "1.7.0_45" on mac os x, using with jruby 1.7.4 and now it works fine.

I tried the neo4j-core api, looks good. I will try the rails app.

arikan commented 10 years ago

Hi Andreas,

I tried your rails app, but it throws the following error, looking for active_support somehow...

In the rails app's Gemfile I removed the path below, which in return installed neo4j (1.3.1 java). This may cause the error, not sure. What should be right reference for the neo4j installation here. In other words, which neo4j libs we need now for a proper rails app?

Hi

Nice that you are testing it. It will not work with Neo4j 1.3.1. You should not edit the Gemfile since we should use the latest unreleased neo4.rb If you pull from github and cd in to the blog folder then the path should be correct.

Otherwise you can build the alpha version by running the Rake task in the root folder (check it Rake -T) Or install it from github 3.0 branch. Both those two options requires you to edit the Gemfile.

Cheers

Thanks Andreas,

It works after installing gem 'neo4j' from github 3.0 branch. And editing the config/application.rb as mentioned here https://github.com/andreasronge/neo4j/wiki/Neo4j-v3

andreasronge commented 10 years ago

Great. Here is the planned API - https://github.com/andreasronge/neo4j/wiki/Neo4j-v3
