我正在尝试设置我的 Heroku 应用，但是当我尝试运行 db:setup、db:create 时，我得到：

[hauleth@NIUNIOBOOK] Tori $ heroku run rake --trace db:setup
Running rake --trace db:setup attached to terminal... up, run.1

如何解决这个问题？我正在使用 Rails 3.1.3 在 Cedar 堆栈上运行。

我已经测试了 Ruby 参见 ENV['DATABASE_URL'] 并且我已经测试了 URI.parse 可以在它上面工作。那么异常在哪里呢？

编辑 这是我在新应用程序中的第一次迁移。我检查了heroku run console 可以访问ENV['DATABASE_URL'] 并且URI#parse 没有抛出任何错误。

Answer 1

您的DATABASE_URL 可能丢失或为零。

检查：

heroku config

如果看起来没问题，请尝试重新添加插件：

heroku addons:remove shared-database:5mb
heroku addons:add shared-database:5mb

Answer 2

我已经通过重新创建完整的 Git 和 Heroku 应用来解决这个问题。
