带有Selenium的Chrome驱动程序：“找不到合适的RemoteWebDriver构造函数”

Question

我正在尝试在Java绑定下将chrome驱动程序与Selenium一起使用。我遵循以下指示：ChromeDriver指示

所以我运行ChromeDriver.exe，将其放在我的代码中WebDriver driver = new RemoteWebDriver("http://localhost:9515", DesiredCapabilities.chrome());，然后出现此错误：

Error:(33, 28) java: no suitable constructor found for RemoteWebDriver(java.lang.String,org.openqa.selenium.remote.DesiredCapabilities)
    constructor org.openqa.selenium.remote.RemoteWebDriver.RemoteWebDriver(org.openqa.selenium.remote.CommandExecutor,org.openqa.selenium.Capabilities) is not applicable
      (argument mismatch; java.lang.String cannot be converted to org.openqa.selenium.remote.CommandExecutor)
    constructor org.openqa.selenium.remote.RemoteWebDriver.RemoteWebDriver(java.net.URL,org.openqa.selenium.Capabilities) is not applicable
      (argument mismatch; java.lang.String cannot be converted to java.net.URL)

如何让Chrome驱动程序正常工作？

编辑：与其他方法：

System.setProperty("webdriver.chrome.driver", "PATH\\chromedriver.exe");
WebDriver driver = new ChromeDriver();

我得到这些错误：

Answer 1

尝试您的代码时出现编译错误 The constructor RemoteWebDriver(String, DesiredCapabilities) is undefined

对于Java，您可以尝试类似的方法，

  System.setProperty("webdriver.chrome.driver","Drive:"+File.separator+"chromedriver.exe");
  driver = new ChromeDriver();
  driver.get(url);
