Question

我一直在跟踪ruby on rails应用程序教程，我一步一步地按照所有内容，但当我到达将我的应用程序上传到heroku的最后一步时，我收到了一条错误消息。我尝试安装它要求的gem，但我仍然会收到相同的错误消息。

$ git push heroku master 计数对象：67，完成。 Delta压缩最多使用4个线程。压缩对象：100％（53/53），完成。书写对象：100％（67/67），26.30 KiB | 0字节/秒，完成。总计67（delta 4），重复使用0（delta 0）

Answer 1

Heroku不再支持SQLite作为数据库，因此您必须切换到Postgres gem：pg。虽然您可以使用sqlite3进行开发并使用postgres进行生产，但不建议使用它，因为您希望尽可能保持开发和生产环境的相似性。

Heroku has a guide让你入门

Answer 2

由于Heroku为您的应用程序提供PostgreSQL数据库，请编辑您的Gemfile并更改此行：

gem'sqlite3' 对此：

gem'pg'

git push heroku master问题。 heroku不允许我上传我的应用程序
