Ruby on rails 3 安装rails插件后无法运行generate语句

我尝试从rails项目根目录安装回形针插件，方法是

rails plugin install http://github.com/thoughtbot/paperclip.git

已成功创建供应商/插件/回形针。但在此之后，我无法运行任何generate（

railsgeneratescaffold

）命令。我得到了错误的答案

通过将此gem作为插件安装，您将无法获得gem所需的依赖项。

回形针

宝石依赖于另一种名为

可卡因

的宝石

我真的建议您安装

回形针

gem，方法是将其放入

gem文件

并运行

bundle安装

这就是为什么你应该使用gems而不是插件。
