ruby on rails 教程第 3.2 节 rspec 测试错误 [英] ruby on rails tutorial section 3.2 rspec testing error

问题描述

最近开始了 Michael Hartl 的 RoRTute，在尝试我在第 3.2 节中的第一个 rspec 测试时陷入困境，此时测试注定要失败，但我得到的只是我很难解释的错误.我环顾四周，但没有找到类似的错误和/或解决方案.我是编程和 ruby​​/rails 的新手.任何帮助将不胜感激，谢谢！

recently started the RoRTute by Michael Hartl, getting stuck trying my first rspec test in section 3.2, at this point the test is meant to fail but all i get are errors which I'm having a hard time interpreting. I've had a look around but not getting much luck finding a similar error and/or solution. I am brand new to programming and ruby/rails. Any help would be greatly appreciated, thank you!

推荐答案

看来您使用的是旧版本的 gem.试试 'selenium-webdriver', '~>2.35.1' 最新版

It seems you are using old version of gem. Try 'selenium-webdriver', '~> 2.35.1' latest
