我正在学习 Rails 3.2 版的Ruby on Rails 教程，并且快到第 5 章的末尾了。虽然它在几天前接受了我的代码，但 Heroku 不再希望在我推送时接受它。它抱怨它需要一个 Gemfile.lock，我可以理解——但我已经提供了一个。

几天前，我确实从存储库中删除了 Gemfile.lock，因为我在 Windows 上启动了这个项目并因此陷入了 Bundler 地狱。当时我在.gitignore中添加了Gemfile.lock的名称，但现在我已经从.gitignore中删除了它的名称并重新添加了它；然而 Heroku 仍然认为它没有被承诺。

我能做些什么？除了在当前阶段重新添加 Gemfile.lock 之外，我还尝试使用变基来删除首先删除它的提交。我还从 Heroku 中完全删除了该应用程序并重新添加了它（使用相同的名称和不同的名称）。此外，虽然我没有在 shell 会话中捕获它，但我确实在bundle update这一切之前运行以确保 Gemfile.lock 与 Gemfile 匹配。

这是我的 bash 会话：

$ type ssha-heroku
ssha-heroku is aliased to `eval `ssh-agent`; ssh-add -t 5m ~/.ssh/heroku.id_rsa'

我最终将问题追溯到这样一个事实，即我根据平台（Mac、Linux 和 Windows）为 Guard 通知指定了不同的 gem；但是当我bundle install在我的 Mac 上运行时，它不会在 Gemfile.lock 中锁定 Linux 或 Windows gem。我在检测主机平台的声明中确实有这些宝石case，但显然 Bundler 无法从中看出我的意图。

我把整个条件都去掉了，只指定了 Mac gems 而不是其他平台。一段时间后，我会进一步调查；由于这些宝石仅用于测试，我认为 Heroku 的 Bundler 根本不需要了解它们。
