Question

有没有人知道在Heroku的Bamboo堆栈上运行使用DataMapper的Sinatra应用程序所需的神奇咒语？ Bamboo堆栈不包含任何预先安装的系统宝石，无论我尝试什么样的宝石组合，我都会遇到此错误：

undefined method `auto_upgrade!' for DataMapper:Module (NoMethodError)

这就是我在.gems文件中的内容：

sinatra
pg
datamapper
do_postgres
dm-postgres-adapter

这些是我将应用程序推送到Heroku时安装的依赖项：

使用SQLite3在本地运行应用程序。我错过了另一个PostgreSQL组件吗？

dm-migrations gem添加了DataMapper.auto_upgrade！。在自动升级之前，您是否需要dm-migrations或datamapper gem？

未定义的方法auto_upgrade！将Sinatra / DataMapper应用程序推送到Heroku时
