您跳过了部分安装说明，即：

我们需要将 Gemfile.lock 切换到 PostgreSQL。编辑Gemfile并更改ENV['DB'] ||= 'mysql'为ENV['DB'] ||= 'postgres'. 然后运行：

bundle --without development test heroku production assets
git add Gemfile Gemfile.lock
git commit -m "switch Gemfile.lock to pg exclusivly"

我相信问题是heroku不支持开箱即用的mysql。您将需要切换到 Postgres 或使用插件，例如ClearDB。

更新：转念一想可能是这个

您收到的有关 Gemfile.lock 的错误消息可能是因为您的 Gemfile 和 Gemfile.lock 彼此不一致。自从您上次运行 bundle install（或更新）以来，听起来您已经更改了 Gemfile 中的某些内容。当您捆绑安装时，它会使用您对 Gemfile 所做的任何更改来更新您的 Gemfile.lock。

确保在本地运行 bundle install，然后签入以控制新更新的 Gemfile.lock 的源代码。然后尝试部署。

编辑：正如评论中所承认的，Gemfile 中的条件导致一个平台上有效的 Gemfile.lock，在另一个平台上无效。在 Gemfile 中为这些平台相关的 gem 提供一个 :platform 标志应该可以解决不对称问题。
