ruby-on-rails – 从Rails 3.2升级到Rails 4时出错

2019年8月4日 147次阅读

升级到Rails 4时遇到以下错误：

Bundler could not find compatible versions for gem "railties":
  In Gemfile:
    rails (= 4.0.0) ruby depends on
      railties (= 4.0.0) ruby

    sass-rails (~> 4.0.0) ruby depends on
      railties (4.0.0.rc2)

我的Gemfile看起来像这样：

source 'https://rubygems.org'
ruby '2.0.0'

gem 'rails', '4.0.0'

gem 'sass-rails',   '~> 4.0.0'
gem 'coffee-rails', '~> 4.0.0'

# Other gems

任何帮助将不胜感激.

最佳答案 问题不在sass-rails声明中.它一定是其他宝石之一.

在我的Gemfile中只包含以下宝石后,一切正常.

source 'https://rubygems.org'
ruby '2.0.0'

gem 'rails', '4.0.0'

gem 'sass-rails',   '~> 4.0.0'
gem 'coffee-rails', '~> 4.0.0'

其中一个宝石必须有一些依赖性问题.当我发现它是哪一个时,我会更新我的答案.
