将 rails 应用程序从“最新稳定”的 rails gem 切换到“bleeding edge”

Question

最近我用“latest table rails”写了一个新应用

但是，存在一些问题，它们在“出血边缘”中得到了修复。

那么我如何告诉我的应用程序使用我认为比“最新稳定”更新的“出血边缘”

Answer 1

Rails 依赖于 arel，因此您需要手动抓取它们。目前这是每个人的最前沿：

gem 'rails', '~> 5.1.0.alpha', github: 'rails/rails', ref: 'abfd091980faaa4404db5fbfdf77c68a35684d08'

gem 'arel', '~> 8.0', github: 'rails/arel', ref: 'd6af2090b16f7d061aa43913d610c6fada58b7e2'

rails/rails commit history

rails/arel commit history

将这些添加到您的 Gemfile 并运行 bundle。

假设没有任何冲突，您应该得到如下所示的输出：

这表明 Rails 处于最前沿：abfd091，目前。

这里应该包括通常的警告词，即在最新的稳定版本上使用前沿是非常危险的！
