Ruby on rails 部署到Heroku时出错（不推荐使用警告：供应商/插件中有Rails 2.3风格的插件）

我在尝试推送到Heroku时出现以下错误。它在localhost:3000上工作，但不确定从哪里开始。我删除了供应商/插件（在本地主机上工作）中的文件，但在尝试上载到Heroku时仍然产生相同的错误

如果您试图删除插件，则需要运行

rails plugin remove[您的插件]

，而不仅仅是删除文件夹

---

另外，我相信heroku在你的应用程序中添加了一些插件，这些插件可能已经过时了。

删除你的供应商/plugins/.gitkeep（如果你有）

将这些行添加到您的文件中

group :production do
  gem 'rails_12factor'
end

运行bundle命令

bundle install

提交文件Gemfile和Gemfile.lock

git add Gemfile Gemfile.lock
git commit -m 'Added gem rails_12factor to avoid warnings on heroku'

推动您的更改，永远摆脱这些警告

git push heroku master

---

我讨厌这个警告，我希望能有一个很好的答案来解决它。它的可能重复很奇怪。在构建应用程序时，我分阶段保存了它。当我尝试将其上传到剥离到基本用户注册/登录的位置时，它似乎起作用，因此我知道是后期的某个原因导致了错误。只是不确定什么？我不知道需要运行该命令来删除文件，所以谢谢你。据我所知，heroku确实向应用程序中注入了插件（heroku自己显然承认这是一个问题），但似乎没有任何直接的文档来解决这个问题。也许我会在rails 4.0中重建应用程序，省去麻烦。

git push heroku master
