如何从 Ruby on Rails 应用程序中删除 gem? [英] How to remove gem from Ruby on Rails application?

问题描述

我在我的 Rails 应用程序(设计)上安装了一个 gem.安装 gem 后，我意识到我不需要它.

I have installed a gem on my Rails application (devise). After I installed the gem, I realized that I don't need it.

我想删除 gem、它的依赖项以及它在我的应用程序上创建的文件.换句话说，我想将系统恢复到宝石之前的状态.我怎样才能做到这一点?(我正在使用 Ruby on Rails 3.)

I want to remove the gem, its dependencies and the files it created on my application. In other words, I want to restore the system to what it used to be before the gem. How can I do this? (I'm using Ruby on Rails 3.)

推荐答案

Devise 使用一些生成器来生成视图并将它需要的东西放入您的应用程序中.如果你已经运行了这个生成器，你可以很容易地撤销它

Devise uses some generators to generate views and stuff it needs into your application. If you have run this generator, you can easily undo it with

rails destroy <name_of_generator>

gem 的卸载工作如其他帖子中所述.

The uninstallation of the gem works as described in the other posts.
