当我沿着这个视频https://www.youtube.com/watch?v=bDjbqRL9HcM走的时候，我来到了一个应该使用rake任务的地方，然后发生了这个事情：

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

rake aborted!

Don't know how to build task 'neo4j:install'

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

我尝试将以下内容放入RakeFile中，这是我运行rails new时创建的：require 'neo4j/tasks/neo4j_server' -它似乎是通过给出以下输出来工作的：

/blog$ rake neo4j:install[community-2.1.5] Installing Neo4j-community-2.1.5 environment: development Neo4j Installed in to neo4j directory

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了

我不知道为什么它会起作用。也许你能给出一个很好的解释？

如果您希望在项目中包含所有neo4j rake任务，请将以下代码添加到Rakefile中：

require 'neo4j/rake_tasks'

这是因为gem ne4j- Rakefile是随neo4j gem自动添加的，但是您仍然需要将它包含在Rakefile中。

在这之后，do: rake -T你应该会看到：

rake neo4j:change_password                   # Neo4j 2.2: Change connection password
rake neo4j:config[environment,port]          # Configure Server, e.g
rake neo4j:disable_auth[environment]         # Neo4j 2.2: Disable Auth
rake neo4j:enable_auth[environment]          # Neo4j 2.2: Enable Auth
rake neo4j:info[environment]                 # Get info the Neo4j Server
rake neo4j:install[edition,environment]      # Install Neo4j with auth disabled in v2.2+
rake neo4j:migrate[task_name,subtask]        # Run a script against the database to perform system-wide changes
rake neo4j:reset_yes_i_am_sure[environment]  # Reset the Neo4j Server
rake neo4j:restart[environment]              # Restart the Neo4j Server
rake neo4j:start[environment]                # Start the Neo4j Server
rake neo4j:start_no_wait[environment]        # Start the Neo4j Server asynchronously
rake neo4j:stop[environment]                 # Stop the Neo4j Server
