安装gem capybara-webkit时出错，出现以下错误：Gem :: Ext :: BuildError：错误：无法生成gem本机扩展

问题描述

在安装gemlock文件时，出现以下错误： 我对Ruby很有经验，但是我想做的只是从github运行该应用程序。这是2015年编写的相当古老的程序（https://github.com/jmopr/job-hunter）

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

An error occurred while installing capybara-webkit (1.15.1),and Bundler cannot
continue.
Make sure that `gem install capybara-webkit -v '1.15.1'` succeeds before
bundling.

In Gemfile:
  capybara-webkit

该项目的目标是从git hub下载并运行ruby on rails应用程序。这是2015年以来的较旧应用程序，这就是为什么我一直遇到这么多依赖问题的原因。以下是我的gem文件，供您进一步参考。

解决方法

很高兴知道您使用的是哪个操作系统。如我所见，它的Windows？

在Mac上，您可能必须安装qtwebkit 在Ubuntu Xvfb上可以提供帮助。 但是IDK如何在Windows上处理此问题
