我还没有找到任何解决方案，我很伤心，因为它的initylla与sqlite3一起工作，但我需要为Heroku部署使用postgresql ...

1 个答案:

答案 0 :(得分：3)

也许这会对你有所帮助： postgreSQL database service

如下面的答案（用户：ontrack）中所述

使用服务（开始 - ＆gt;运行 - ＆gt; services.msc）并查找postgresql- [version]服务。

  • 如果不存在，您可能刚刚安装了pgAdmin而没有安装PostgreSQL本身。
  • 如果它没有运行，请尝试启动它，如果它无法启动，请打开事件查看器（start - ＆gt; run - ＆gt; eventvwr）并查找与PostgreSQL服务相关的错误消息。
  • 如果它确实开始检查启动类型，如果你想从Windows开始它应该是“自动”;如果您不希望它太慢地降低启动速度，可能还是“自动，延迟启动”。
