为“carrierwave_backgrounder:install”创建生成器时出错

Question

我正在为“carrierwave_backgrounder:install”创建一个生成器，以便在S3中处理我的图像。然而，我陷入了一个问题。

1. 当我使用gem 'carrierwave_backgrounder'时，我会得到错误

Could not find generator 'carrierwave_backgrounder:install'. Maybe you meant 'rspec:install', 'exception_notification:install' or 'active_record:model

• 当我按照给出的建议使用gem 'carrierwave_backgrounder', git: 'https://github.com/lardawge/carrierwave_backgrounder'并运行包安装或包更新时，我将得到错误Bundler could not find compatible versions for gem "mime-types": In snapshot (Gemfile.lock): mime-types (= 3.3)

In Gemfile: carrierwave-base64 (= 2.6.1) was resolved to 2.6.1, which depends on mime-types (~> 3.0) carrierwave_backgrounder was resolved to 0.4.2, which depends on mime-types (~> 2.99)

而且我的包更新也无法解决错误。我该怎么解决这个问题？

Answer 1

将行'carrierwave_backgrounder',git:'https://github.com/lardawge/carrierwave_backgrounder'改为gem 'carrierwave_backgrounder', github: 'lardawge/carrierwave_backgrounder', ref: 'bff7bc3954b9184157812f948b9a6a4f64ff36d3'解决了这个问题。
