无法接收来自渲染器的消息

我刚开始学习 Selenium，但我的 chromedriver 版本似乎与我当前的 chrome 版本不兼容？如能提供任何帮助，我将不胜感激

以下是我收到的错误消息：

Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.
[1556601048.968][SEVERE]: Unable to receive message from renderer

我的原始代码：

 package com.selenium.webdriver.basic;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class First {
    /**
     * webdriver is a thing where all my functions are
     * which is going to control the browser 
     * and manages the functions which will let me the browser's property
     */
    WebDriver driver;   


    public void invokeBrowser() {
        try {
            System.setProperty("webdriver.chrome.driver", "C:\\Selenium_tutorial\\chromedriver_win32\\chromedriver.exe");
            driver = new ChromeDriver();  //instantiate your chrome driver
            driver.manage().deleteAllCookies();//use driver as object reference
        //  driver.manage().window().maximize(); //always minimize by default

            //bait synchronization. always need this 
            driver.manage().timeouts().implicitlyWait(3600, TimeUnit.SECONDS); //element detection timeout
            driver.manage().timeouts().pageLoadTimeout(3600, TimeUnit.SECONDS);


            driver.get("https://www.google.ca/");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        First myObj = new Fisrt();
        myObj.invokeBrowser();

    }

}

这可以与旧版本的 Selenium 一起使用，但您应该添加一行并修改另一行以使用 ChromeOptions。我正在执行这个“空中代码”，因此它可能不是 100% 准确：

ChromeOptions option = new ChromeOptions();
driver = new ChromeDriver(options);

您的 IDE 应该提示您包含 ChromeOptions 库，我不知道它是什么，或者我也会为您包含它。

此外，虽然页面和元素超时很重要，但您将两者都设置为一小时 - 对于超时失败来说太长了。我建议将它们设置为更现实的时间，例如 15 到 30 秒。
