Answer 1

基于例外情况，您使用的是 selenium-webdriver 版本 2.33.0。我猜这个版本和你的 chromedriver 不兼容。

假设您使用的是最新的 chromedriver，您可能需要更新到最新的 selenium-webdriver，即 2.35.1 版本。

试一试：

gem install selenium-webdriver

下载新的 chrome 驱动程序 http://chromedriver.storage.googleapis.com/index.html?path=2.4/

我遇到了同样的问题并更新了 chrome 驱动程序，问题得到了解决。我还更新了我的宝石。
