在先前将Gemfile.lock从存储库中取出后，将Rails应用程序部署到Heroku

我正在学习的是Rails 3.2版，第5章即将结束。虽然几天前它接受了我的代码，但Heroku不再想在我推的时候接受它。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，并因此遇到了Bundler地狱。当时，我将Gemfile.lock的名称添加到了.gitignore中，但现在我已将其名称从.gitignore中删除并重新添加；然而，赫罗库仍然认为这是没有承诺的

我能做什么？除了在当前阶段重新添加Gemfile.lock之外，我还尝试使用重定基来删除一开始删除它的提交。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，尽管我没有在shell会话中捕获它，但在所有这些之前，我确实运行了

bundle update

，以确保Gemfile.lock与Gemfile匹配

下面是我的bash会话：

我最终将问题追溯到这样一个事实：我根据平台（Mac、Linux和Windows）为防护通知指定了不同的gem；但是当我在Mac上运行

bundle install

时，它不会将Linux或Windows gems锁定在Gemfile.lock中。我确实在一个检测主机平台的

案例

语句中包含了这些宝石，但显然Bundler无法从中分辨出我的意图

我去掉了所有条件，只指定了Mac gems，而不是其他平台。在今后的某个时候，我将进一步调查；由于这些gem仅用于测试，我认为Heroku的Bundler根本不需要了解它们。
