我刚刚在Heroku上创建了一个app来安装我的rails应用程序，我正试图第一次推送。似乎很多事情都失败了，但我不确切知道是什么。这是日志：

我尝试手动安装sqlite3版本1.3.11并且安装得很好，但是我仍然遇到错误。我还尝试运行apt-get install libsqlite3-dev行来解决丢失的sqlite3.h文件问题，但该软件包已经安装。我还尝试运行rake assets:precompile预先编译应用程序，然后再将其上传到heroku，这是我在另一篇文章中读到的内容。

Heroku不支持sqlite：https://devcenter.heroku.com/articles/sqlite3
您需要使用postgresql数据库设置您的应用程序才能在Heroku上运行：https://devcenter.heroku.com/articles/heroku-postgresql#connecting-in-ruby
