我在簡單程式中遇到錯誤，之前它運行良好，現在由于某種原因我無法執行它。我正在使用 selenium 3.0.1 Chrome 驅動程式 93.0.4 請檢查我的代碼和下面的錯誤。
如果有人可以幫助我，將不勝感激
我的代碼：
public class MouseOverDemo {
public static void main(String[] args) {
System.setProperty("webdriver.chrome.driver", "C:\\SeleniumJars\\chromedriver.exe");
WebDriver driver = new ChromeDriver();
// JavascriptExecutor js = (JavascriptExecutor)driver;
//driver.get("http://demo.guru99.com/test/drag_drop.html");
driver.get("https://jqueryui.com/resizable/");
Actions action = new Actions(driver);
WebElement resize = driver.findElement(By.cssSelector("body.jquery-ui.page.page-id-43.page-template-default.page-slug-resizable.single-author.singular:nth-child(2) div:nth-child(2) div.clearfix.row:nth-child(3) div.content-right.twelve.columns div:nth-child(1) > iframe.demo-frame:nth-child(5)"));
driver.switchTo().frame(resize);
WebElement resize1 = driver.findElement(By.id("resizable"));
action.moveToElement(resize1, 2500, 2500).build().perform();
System.out.println("Resize is done");
}

...暗示ChromeDriver無法啟動/生成新的Google Chrome 瀏覽背景關系。
您的主要問題是您使用的二進制檔案版本之間的不兼容。雖然您使用的是最近的 ChromeDriver v93.0.4577.63之一，但Selenium版本是3.0.1，這是古老而古老的。
解決方案
確保這件事：
- JDK升級到當前級別JDK 8u311。
- Selenium升級到當前級別Version 4.0.0。
- ChromeDriver更新到當前ChromeDriver v95.0級別。
- Chrome已更新到當前的Chrome 版本 95.0級別。（根據ChromeDriver v78.0 發行說明）
- 進行系統重啟。
- 以非 root用戶身份執行@Test。
- 始終
driver.quit()在tearDown(){}方法內呼叫以優雅地關閉和銷毀WebDriver和Web Client實體。
