尝试推送到heroku然而我得到Push拒绝，无法编译ruby应用程序。 （详见下文）任何想法从哪里开始？我想我必须从安装sqlite 1.3.8 gem开始，但是sqlite3 1.3.8 gem在我的本地gem列表（RVM）中。感谢!!!

You can't use SQLite on Heroku，你必须使用PostgreSQL。
您可以将其设置为在Heroku上使用PostgreSQL，但在开发中使用SQLite，在开发和生产环境中使用相同的数据库是一种很好的做法。

从日志中查看这些行：
! Detected sqlite3 gem which is not supported on Heroku.
! https://devcenter.heroku.com/articles/sqlite3
你需要在Heroku上使用Postgres来获取RDBMS。或者您可以选择MongoDB和Neo4J以及非关系数据存储。
