同样的代码在FireFox中运行良好

我附上屏幕截图来展示它的外观。

您正在使用ChromeDriver v2.1和ChromeV30

将ChromeDriver更新至最新版本，2.1版不支持Chrome30

---

其结果是，任何调用（包括导航）都不起作用，因此任何find元素调用也会出错。

首先，如果您将

xpath

或

选择器签入，比如Firebug，是否真的起作用？如果是，请尝试此选项

new Actions(driver).moveToElement(driver.findElement(By.cssSelector("selector")))
    click.perform();

你能在启动Chromedriver后很快加载url吗？没有帮助。使用端口上的启动ChromeDriver（v2.4.226107）复制23838@DimaStar…如果问题没有解决，你为什么要求关闭这个？无论如何，发布用于创建驱动程序实例的代码。ChromeOptions options=new ChromeOptions（）；options.addArguments（UtilConstants.ANDROID\u USER\u AGENT）；这个.setDriver（新的ChromeDriver（选项））；我要求关闭这个bug，因为在我们调用findBy元素之前发现问题发生了。它发生在我们查找页面上不存在的元素时。所以我的错误描述是错误的。
