我需要将 rails_12factor gem 安装到我的应用程序的 gem 文件中，以便成功部署到 Heroku。我能够安装 gem (gem install rails_12factor)，如果我运行 gem list 它显示它是在本地安装的。如何将特定的 gem 安装到我的包中？不确定我问的是否正确，但正如您在下面看到的，它是在本地安装的，正如我所说。

我能够在此路径 C:\Users\vern.gem\specs\rubygems.org%443\quick\Marshal.4.8 中找到 rails_12factor-0.02.gemspec
我注意到它是一个 gem 规范文件，但是我不知道如何将它安装为我的项目的 gem 包的一部分
以下是我推送到heroku时得到的结果：
c:\dev\project2>git push heroku master

如您所见，它删除了 rails_12 因素 gem，所以我不太确定该怎么做。我也收到警告
警告：包含“rails_12factor”gem 以启用所有平台功能有关更多信息，请参阅https://devcenter.heroku.com/articles/rails-integration-gems。也许有一个我没有意识到任何帮助的解决方案将不胜感激。谢谢
