可能重复：
eliminating Rails 2.3-style plugins and deprecation warnings

我在执行heroku run console 时收到以下错误：

$ heroku run console
Running `console` attached to terminal... up, run.1
DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed in Rails 4.0. Move them out an d bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb. See the release notes for more on this: http://weblog.rubyonrails.org/2012/1/4/rails-3-2-0-rc2-has-been-released. (called from <top (required)> at /app/config/environment.rb:5)

但是，我在供应商/插件中的唯一文件是 .gitkeep:

$ ls -lha vendor/plugins/
total 0
drwxr-xr-x    1 Scott    Administ        0 Sep  7 12:26 .
drwxr-xr-x    1 Scott    Administ        0 Sep  7 12:26 ..
-rw-r--r--    1 Scott    Administ        0 Sep  7 12:26 .gitkeep

我什至尝试删除 .gitkeep 文件，但仍然收到相同的弃用警告。我有坏插件吗？这是一个相对较新的 Rails 项目。

【解决方案1】：

Heroku 注入旧式插件以使您的应用程序在其服务器上运行（特别是将日志重定向到标准输出，并从 rails 提供静态资源）。检查git push 的输出...您会看到类似这样的内容

-----> Rails plugin injection
       Injecting rails_log_stdout
       Injecting rails3_serve_static_assets

所以这不是你做过的事情，也没有什么好担心的！这些在 Rails 3.x 上运行得很好，当 Rails 4 更成熟一点时，Heroku 无疑会解决一些问题。
