chromedriver 与 google-chrome 版本用法说明，例：

我的服务版本是 Google Chrome 73.0.3683.103

从这个地方下的不行包有问题 http://chromedriver.storage.googleapis.com/index.html

到此处下载 ：http://npm.taobao.org/mirrors/chromedriver

 

有版本 73.0.3683.20 和 73.0.3683.68  

这两个都不是 我用了  2.46  

对应的关系表可以上百度下可以找到很多

还有就是记行加入 chmod 777 chromedriver 

注 Linux 下加入 

ChromeOptions chromeOptions=new ChromeOptions();
if(MySystem.isLinux()) {
    chromeOptions.addArguments("headless");//无界面参数
    chromeOptions.addArguments("no-sandbox");//禁用沙盒 就是被这个参数搞了一天
}

补冲

1. 记得安装 google 浏览器

后来又装了一台服务器怎么搞都不成功：

我 直接下了：

wget https://chromedriver.storage.googleapis.com/2.40/chromedriver_linux64.zip

unzip chromedriver_linux64.zip

2.4的居然成功了

我认为可能是我用windows下的，所以出了问题，以后用linux  直接下直接用，再试试
