ruby - Rake 使用 neo4j :install[community-2. 1.5 中止]

Question

所以我一直在关注这个视频 https://www.youtube.com/watch?v=bDjbqRL9HcM我来到了我应该使用 rake 任务的部分然后发生了这件事:

blog$ rake neo4j:install[community-2.1.5] --trace

rake aborted!

Don't know how to build task 'neo4j:install'
/home/james/.rvm/gems/ruby-2.1.3/gems/rake-10.3.2/lib/rake/task_manager.rb:62:in `[]'

我在 Ubuntu 14.04 上试过这个。我已经安装了 rvm.io。对我如何解决这个问题有什么建议吗？

Answer 1

我试图将以下内容放入 RakeFile 中，它是在我运行 rails new 时创建的:require 'neo4j/tasks/neo4j_server' - 它似乎通过提供以下输出来工作:

/blog$ rake neo4j:install[community-2.1.5]
安装Neo4j-community-2.1.5环境: development Neo4j安装到neo4j目录

我在 application.rb 中添加了以下内容:require 'neo4j/railtie' - 我现在可以使用 rails generate scaffold User name:string email:string

我不知道为什么会这样。也许你能给出一个很好的解释？
