You're using a very old version of neo4j-rake_tasks, and I think it's broken. Have you tried to bundle update neo4j-rake_tasks?

[cheerfulstoic]

I think that 0.7.3 is the latest version of neo4j-rake_tasks, unfortunately:

https://rubygems.org/gems/neo4j-rake_tasks

@prashantkb I haven't been able to test the gem on Windows for a while because of my computer situation, though I hope to be able to in the near future. If you're using Windows 10 you might be able to update to the Anniversary edition and use the new built-in bash shell:

http://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/

But it looks like we didn't implement the install method to take an argument:

https://github.com/neo4jrb/neo4j-rake_tasks/blob/master/lib/neo4j/rake_tasks/windows_server_manager.rb#L15

Which it's supposed to do (the argument is the edition_string):

https://github.com/neo4jrb/neo4j-rake_tasks/blob/master/lib/neo4j/rake_tasks/server_manager.rb

Another, probably easier option, is to simply download Neo4j via their website:

http://neo4j.com/download

The rake tasks are there to provide a way to manage Neo4j servers from the command line, but they aren't required

Hello Sir,

as i m getting error while installing neo4j from command prompt its was giving error..

so as u suggested another option to download the neo4j from http://neo4j.com/download
i download it and installed on my computer and it started at http://localhost:7474

so its worked fine ...

after that i added These two configuration options in the railsproject/config/development.rb
config.neo4j.session_type = :server_db
config.neo4j.session_path = 'http://localhost:7474'

after that i generated the model

$ rails g model Asset title:string created_at:datetime updated_at:datetime

but its giving the error -

I Resolved the error by Adding

require 'neo4j/railtie'

in railsproject/config/application.rb file

[cheerfulstoic]

I'm glad it got figured out! We've also got instructions for different sorts of setups if you run into anything else:

http://neo4jrb.readthedocs.io/en/7.1.x/Setup.html

Of course feel free to let us know if you still can't figure it out

[cheerfulstoic]

Closing this issue in favor of neo4jrb/neo4j-rake_tasks#35
