执行 heroku run console 时出现以下错误:

$ 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.

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，我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。

Heroku 注入(inject)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 Assets )。检查 git push 的输出...你会看到这样的东西

-----> 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 上工作得很好，当 Rails 4 更成熟一点时，Heroku 无疑会解决一些问题。
