可能重复：
Rails 2.3-style plugins and deprecation warnings running task in Heroku

我正在运行rake db：migrate会给我以下警告，然后中止：

$ heroku rake db:migration --trace

当我检查vendor/plugins文件夹时，我只找到一个名为.gitkeep的文件并且为空

Answer 1

作为一个FYI，以防由于问题标题而人们从搜索引擎到达此处。弃用警告是由Heroku注入插件引起的 - 请参阅Jared Beck对此问题的回答：Rails 2.3-style plugins and deprecation warnings running task in Heroku

以上nzifab提出的解决方案对于潜在问题有效，但这不是问题标题中提出的问题

Answer 2

vendor/plugins这里不是问题，那些只是警告。这是heroku run rake db:migrate ..

如果你不在Cedar堆栈上，那么

可能只是heroku rake db:migrate（注意migrate，而不是migration）

Answer 3

我的感受是，您必须在任何gems中进行一些更改，并将层次结构和文件复制到“..app / vendor / plugins”文件夹中。

如果是这种情况，那么这只是一个警告，告诉你应该在“lib”文件夹中复制插件。当你开始使用webrick时，你必须看到相同的结果。

弃用警告：您在供应商/插件中拥有Rails 2.3风格的插件！支持将在Rails 4.0中删除
