无法使用 selenium webdriver 在 Mac 上启动 Chrome

Question

我想在 MAC Chrome 上运行我的脚本。我执行了以下步骤

1. 从http://chromedriver.storage.googleapis.com/index.html下载最新的chrome驱动
2. 解压后将文件复制到/usr/bin

在 irb 上我执行了以下步骤

require 'selenium-webdriver'
driver = Selenium::WebDriver.for :chrome

它给出以下错误信息

下载最新版本的 chromedriver 并将其保存在 usr/local/bin 中并运行您的代码它会起作用，因为同样的事情适用于我....如果您想查看正在运行的版本然后转到您的 chromedriver 并正确单击并使用终端打开。它会向您显示版本，因此请记住您的版本应该是 2.15.XXXXXX

我很确定它对你有用！
