我在使用以下 Gemfile 为 Ruby 项目运行

bundle install

时遇到问题：

ruby '2.3.1'

source 'http://www.rubygems.org'

gem 'aws-flow', '~> 2.4.0'
gem 'aws-sdk-core', '~> 3.65', '>= 3.65.1'

安装

unf_ext

gem 时出现错误，并显示以下消息：

我已按照建议检查了 mkmf.log 文件，但我无法确定为什么安装

unf_ext

gem 以及可能导致此编译错误的原因。我没有在 Gemfile 中明确包含

unf_ext

，它似乎是另一个 gem 的依赖项。

任何有关如何解决此问题的指导或有关安装

unf_ext

原因的见解将不胜感激。另外，是否有特定版本的宝石需要调整？

目前的修复方法是将其添加到您的 Gemfile 中，暂时固定旧版本，直到此票证有可用的修复程序为止。 https://github.com/knu/ruby-unf_ext/issues/74

gem 'unf_ext', '= 0.0.8'
