使用 Ruby 1.9.3 和 Rubygems 1.8.15 安装 webrat

Question

我想将 webrat 与 Cucumber 结合使用来为 Web 应用程序编写验收测试。当我尝试安装 webrat gem 时，出现以下错误。我尝试删除 C:\Ruby193\lib\ruby\gems\1.9.1\cache* 和 gem update --system 但没有任何运气。

我正在尝试在 Windows7 环境中在 Ruby 上安装 gem。据我所知，问题与此相关：“在 C:/Ruby193/lib/ruby/gems/1.9.1/cache/webrat-0.7.3.gem 中找不到元数据”

非常感谢任何帮助，谢谢你！

gem install webrat --debug

看起来更新到 Rubygems 1.8.17 可以解决这个问题。 OP使用了update_rubygems。
