Question

我正在研究Ruby on Rails Tutorial的Rails 3.2版本，并且接近第5章的末尾。虽然几天前它接受了我的代码，但Heroku不再想在我推动时接受它。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而遇到了Bundler地狱。那时，我将Gemfile.lock的名字添加到了.gitignore，但是现在我已经从.gitignore中删除了它的名字并再次添加了它。然而Heroku仍然认为它没有承诺。

我该怎么办？除了在当前阶段重新添加Gemfile.lock之外，我还尝试使用rebasing来删除首先删除它的提交。我还完全从Heroku中删除了应用程序并重新添加（使用相同的名称和不同的名称）。另外，虽然我没有在shell会话中捕获它，但我确实在所有这些之前运行bundle update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'

Answer 1

我终于追溯到这个问题，我根据平台（Mac，Linux和Windows）为Guard通知指定了不同的gems;但是当我想要在我的Mac上运行bundle install它不会锁定Gemfile.lock中的Linux或Windows宝石。我确实在case语句中检测到主机平台的那些宝石，但显然Bundler无法完全说出我的意图。

我把整个条件拿出去，只是指定了Mac宝石，而不是其他平台。一段时间后，我将进一步调查;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。

之前从存储库中取出Gemfile.lock之后，将Rails应用程序部署到Heroku
