我試圖使用neo4j gem部署到Heroku的jruby rails應用程序。本地運行工作正常,但當我打#NEW(//新)在Heroku的結束,我得到:Neo4j在部署到Heroku後未自動啓動
NoMethodError (undefined method `reference_node' for nil:NilClass):
之後[一些研究] [1],這似乎是我的Neo4j服務器甚至沒有運行。
所以我不得不這樣做
heroku run rails console
然後
Neo4j.start
..in爲了讓我的應用程序工作。但爲什麼Neo4j不知道只是醒來並開始?
這是我Gemfile.lock的:
