git push heroku master w/error：未能将一些参考推送到“git@heroku.com:floating-woodland-1763.git”[重复]

Question

可能重复：
Heroku, Rails 3 and sqlite3

我使用的是 Centos 6.3 操作系统，但在使用 Git 将我的应用程序推送到 heroku 时遇到问题

我输入的内容：

git push heroku master

我得到了什么：

自从我检查并仔细检查后，我肯定安装了 sqlite3 版本 1.3.6。 我也跑了，得到：

git remote -v
heroku  git@heroku.com:floating-woodland-1763.git (fetch)
heroku  git@heroku.com:floating-woodland-1763.git (push)
origin  git@github.com:(user)/first_app.git (fetch)
origin  git@github.com:(user)/first_app.git (push)

我不知道该怎么做，请帮忙。 =)

你不能在 Heroku 上使用 sqlite。他们提供 PostgreSQL 的免费开发版本。你可以在他们的网页界面或命令行上设置它：

heroku addons:add heroku-postgresql:dev

当然，您使用这个数据库是有限制的，因为当您的应用程序达到一定大小时 Heroku 开始向您收费。您需要获取插件的登录凭据。最简单的方法是访问 Heroku.com 上的应用程序，单击 PG 插件，然后从下拉列表中选择“Active Record”。这实际上会在您的 config/database.yml 文件中显示您连接到 Heroku DB 所需的 YAML。

您需要将gem 'pg' 添加到您的gemfile。 Heroku 建议您在您的开发机器上安装 PG，但如果您不想这样做，您可以在 group :production 下添加 pg gem。

底线：你不能在 Heroku 上使用 sqlite。如果这会破坏交易，请查看 Amazon EC2 或其他数千个托管站点中的任何一个。
