neo4jrbをrubyに導入できない　Neo4j::Core::CypherSession::ConnectionFailedError: Connection failure

前提・実現したいこと

railsにneo4jを導入したいです。
https://qiita.com/yudedako/items/072df2838b79162db5e7
このサイトの通りに実装しているのですが、途中のActiveNodeのところで次のようなエラーが出てしまいます。

¢ noglob bundle exec rake neo4j:migrate

config.eager_load is set to nil. Please update your config/environments/*.rb files accordingly:

  * development - set it to false
  * test - set it to false (unless you use a tool that preloads your test environment)
  * production - set it to true

WARNING: `Faraday::Connection#basic_auth` is deprecated; it will be removed in version 2.0.
While initializing your connection, use `#request(:basic_auth, ...)` instead.
See https://lostisland.github.io/faraday/middleware/authentication for more usage info.

rakeの所はそのままだと上手くいかなかったので、

これを参考にしてnoglobを使っています。
どのように変更すればいいのでしょうか。
