Answer 1

我认为问题是heroku不支持开箱即用的mysql。您需要切换到Postgres或使用插件，例如ClearDB。

更新：第二个想法可能是this

您收到的有关Gemfile.lock的错误消息可能是因为   你的Gemfile和Gemfile.lock不同意。听起来   就像你上次运行以来你在Gemfile中改变了一些东西   捆绑安装（或更新）。捆绑安装时，它会更新您的   Gemfile.lock包含您对Gemfile所做的任何更改。

确保在本地运行bundle install，并签入源代码   之后控制新更新的Gemfile.lock。然后试试   展开。

编辑：正如评论中所认识到的那样，Gemfile中有条件   在一个平台上导致有效的Gemfile.lock，在另一个平台上无效。   为这些平台相关的宝石提供：平台标志   Gemfile应该解决不对称问题。

您跳过部分installation instructions，即：

我们需要将Gemfile.lock切换到PostgreSQL。修改Gemfile并将ENV['DB'] ||= 'mysql'更改为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"

在heroku上部署diaspora时出错无法通过Bundler安装gem
