Try setting an implicit wait of maybe 10 seconds.
尝试设置可能 10 秒的隐式等待。
gmail.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
Or set an explicit wait. An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. In your case, it is the visibility of the password input field. (Thanks to ainlolcat's comment)
或者设置显式等待。显式等待是您定义的代码，用于在进一步处理代码之前等待特定条件发生。在您的情况下，它是密码输入字段的可见性。（感谢ainlolcat的评论）
WebDriverWait wait = new WebDriverWait(gmail, 10);
WebElement element = wait.until(
ExpectedConditions.visibilityOfElementLocated(By.id("Passwd")));
gmail.findElement(By.id("Passwd")).sendKeys("xyz");
Explanation:The reason selenium can't find the element is because the idof the password input field is initially Passwd-hidden. After you click on the "Next" button, Google first verifies the email address entered and then shows the password input field (by changing the id from Passwd-hiddento Passwd). So, when the password field is still hidden (i.e. Google is still verifying the email id), your webdriver starts searching for the password input field with id Passwdwhich is still hidden. And hence, an exception is thrown.
说明：selenium 找不到元素的原因是因为id密码输入字段的 最初是Passwd-hidden。单击“下一步”按钮后，Google 首先验证输入的电子邮件地址，然后显示密码输入字段（通过将 id 更改Passwd-hidden为Passwd）。因此，当密码字段仍处于隐藏状态时（即 Google 仍在验证电子邮件 ID），您的网络驱动程序将开始搜索 idPasswd仍处于隐藏状态的密码输入字段。因此，抛出异常。

Thread.sleep(); worked for me .
线程.sleep(); 对我来说有效。
WebDriver driver=new FirefoxDriver();
driver.get("https:www.google.com");
driver.findElement(By.linkText("Gmail")).click();
driver.findElement(By.linkText("SIGN IN")).click();
driver.findElement(By.id("Email")).sendKeys("abcde");
driver.findElement(By.id("next")).click();
Thread.sleep(2000);
WebElement password = driver.findElement(By.xpath(".//*[@id='Passwd']"));
password.sendKeys("xyzzz");
driver.findElement(By.id("signIn")).click();
Thread.sleep(4000);
driver.close();

driver.get("http://mail.google.com");
driver.findElement(By.xpath("//input[@id='identifierId']")).sendKeys("emaild");
driver.findElement(By.xpath("//span[contains(text(),'Next')]")).click();
Thread.sleep(2000);
WebElement passwordEnter = driver.findElement(By.xpath("//input[@name='password']"));
passwordEnter.sendKeys(password);
driver.findElement(By.xpath("//span[contains(text(),'Next')]")).click();
