弃用警告：你的Rails 2.3风格的插件，供应商/插件！支持将在Rails的4.0 [复制]

可能重复：
Rails的2.3式的插件和在Heroku上运行的任务废弃警告

我正在耙分贝：迁移给我下面的警告，然后中止：

$ heroku rake db:migration --trace

当我检查vendor/plugins文件夹，我只找到一个名为.gitkeep是空的

Answer 1:

vendor/plugins是不是问题就在这里，那些只是warnins。它heroku run rake db:migrate ..

可能只是heroku rake db:migrate ，如果你不是雪松堆栈（注意migrate ，而不是migration ）

Answer 2:

作为一个供参考的情况下，人们来到这里，从搜索引擎，由于问题的标题。弃用警告是由注射的Heroku插件引起的-见贾里德·贝克对这一问题的回答： Rails的2.3式的插件和在Heroku上运行的任务废弃警告

通过上述nzifab提出的解决方案是有效的根本问题，但这是不是在这个问题标题提出

Answer 3:

我觉得这是，你必须作出任何宝石的一些变化和复制的层级，并在“..app /供应商/插件”的文件夹更改的文件。

如果是这样的话，那么这只是一个警告，告诉你应该在“LIB”文件夹复制插件。当你开始在开发模式下的WEBrick你一定看到了同样的。
