推送到 heroku 失败！ （Michael Hartle Rails 教程 3 - 示例应用程序）
Failure to push to heroku! (Micharl Hartle Rails Tutorial 3 - Sample App)
注意：绝对初学者。我注意到大多数类似问题的答案都指出 SQlite3 不适用于 Heroku，并建议使用 PostgreSQL。在朝那个方向做出任何改变之前，我想知道这样做是否会影响我 follow/understand 教程的能力？
我正在使用作者提供的最新 gem 文件。它于 2015 年 11 月 25 日更新。（这就是为什么我很惊讶它包含 SQlite3 gem？）
我是一个绝对的初学者，2 天前才开始学习编程。（解释和解决方案将不胜感激。（使用尽可能简化的语言）谢谢！

如果 SQlite3 gem 在省略的生产组中，就像前面练习中的情况一样，为什么只在本练习中发生这种情况？
Heroku 不支持SQLite，你需要切换到PG。使用 PG 不会影响您学习本教程的能力，因为 ActiveRecord 抽象了 low-level database-specific 命令。
您只需要确保您没有依赖 SQLite 特有的任何功能或行为。
