Question

在部署到Heroku时，我收到一组关于vendor / plugins文件夹的弃用警告（见下文）。我有一个.gitkeep声明，没有别的。有什么我需要做的吗？

Answer 1

Heroku已经指出了这一点，他们已经在为Rails 4开发它了

Heroku通过注入插件来工作，这会导致这种情况发生

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

Rails 2.3-style plugins and deprecation warnings running task in Heroku

Answer 2

我刚刚注意到Heroku现在有一个解决方法。

   Injecting plugin 'rails_log_stdout'
   Injecting plugin 'rails3_serve_static_assets'
   Add 'rails_12factor' gem to your Gemfile to skip plugin injection
