【问题描述】：

我在其他一些问题中寻找解决问题的方法，但即使将它们应用于我的案例，我也无法让 heroku 工作。我正在关注 railstutorials.org 并在调用时收到以下日志（有错误）

git push heroku master

我在安装了 MacPort、Brew 的 Mac OS X 10.9.4 上运行我的代码，我卸载了 postgresql 并重新安装了它，我已经更新了 Xcode 命令行工具，我也刚刚更新了所有 ruby 库。我得到了什么：

我应该怎么做才能让 heroku 与我的代码和库一起工作？提前谢谢你

【问题讨论】：

您需要从 gemfile 中删除 Sqlite

标签： ruby-on-rails ruby macos heroku sqlite

【解决方案1】：

Heroku 建议在您的 gemfile 中使用 Posgres。

用gem 'pg'代替gem 'sqlite3'。
