將chrome驅動程序版本升級到2.28他們解決了此問題。 – Akarsh

升級到最新chromedriver。

這是一個錯誤，並在chromedriver v2.28解決。參見：https://sites.google.com/a/chromium.org/chromedriver/downloads

令人驚歎！解決了我的頭痛 – Priya

嘗試：

System.setProperty("webdriver.chrome.driver", "\\path\\to\\chromedriver");

和不furget添加selenium.jar到您的構建路徑

我也面臨着同樣的問題最近。我從https://chromedriver.storage.googleapis.com/index.html?path=2.29/中取出了最新的jar，並添加到我的項目中。問題解決了。

屏幕閃爍也可能導致此錯誤。

解決方案將窗口大小縮小到屏幕變得穩定。我可以通過添加以下代碼來解決此問題

Dimension d = new Dimension(800, 600); 
driver.manage().window().setSize(d);
