我正在升级到Neo4j.rb版本8。 按照升级指南中的说明操作后，之前通过的规格现在失败。
具体来说，count、persisted?、all、last和find似乎彼此精神错乱。 我可以创建一个帐户，看到它是持久的，如果我计算帐户，则查看它，但如果我查找最后一个帐户或所有帐户，或者尝试从其 id 中找到它，则不会。
下面控制台会话的输出。 我疯了吗？
[1] pry> account = Account.create(company_name: "Acme Corporation, LLC", street_address: "1234 Fake Lane", city: "Pleasantville", state: "CA", zip: "12345", country: "United States", phone: "555-555-5555", contact_name: "Some Guy", contact_phone: "123-456-7890", contact_email: "someguy@acmecorp.com")

答案是.......重新启动计算机，一切正常!!111
实际上，问题在于我删除了数据库而不是停止它，然后安装了一个新副本。
