我正在关注 http://onemonth.com的教程,在那里我创建了我的rails应用程序.我被要求使用Heroku让我的应用程序在线直播.我按照通过SSH密钥将我的Github帐户链接到Heroku的步骤. 但是,当我使用命令
但是,当我使用命令heroku创建然后复制过去提供的链接时,在本例中为 http://young-peak-7631.herokuapp.com/,我在浏览器中收到“应用程序错误”.
这是确切的消息：
“应用程序中发生错误,无法提供您的页面.请稍后再试.如果您是应用程序所有者,请查看日志以获取详细信息.”
请参阅下面的Heroku错误页面图片

我看了一下这个问题的答案.大多数人都说Heroku不支持sqlite3,我需要将我的数据库转换为PostgreSQL

D B您的问题几乎肯定与数据库相关(正如您已经建议的那样)
Heroku有两种类型的错误 – 标准的“Rails”错误& Heroku平台错误：
Rails错误
Heroku错误
–
错误
这些错误是在Heroku上运行的Rails应用程序的标准 – 不同之处在于Rails错误是从Rails应用程序本身派生的错误; Heroku错误是从Heroku平台提出的
Heroku错误本质上意味着您的应用程序由于某种原因无法加载;通常是因为它无法连接到您的数据库,或者数据库没有正确的数据表.
要解决这个问题,首先需要确保使用database in production(强烈建议使用Heroku的Postgres DB)：
#config/database.yml production: ....
你有这个设置和&推送到Heroku,然后需要确保使用正确的表填充数据库.要执行此操作,请在本地cmd中运行heroku run rake db：migrate
更新
确保您拥有生产数据库的方法是使用Heroku Postgres db,这应该是您的Heroku应用程序仪表板中的标准配置
如果您需要将Heroku postgres数据库添加到仪表板,则只需要add the add-on here
数据库出现在您的信息中心后,点击它&它应该提出Postgres界面.你可以看到how to connect to the db in Ruby here;您应该在应用程序的仪表板中使用Postgress附加组件提供的详细信息
通常,Heroku兼容的database.yml看起来像这样：
