原因一：
没有设置chrome driver的位置
//设置driver位置的方法。
System.setProperty(“webdriver.chrome.driver”, “/Users/supinrong/code/driver/chromedriver”);
原因二：
guava版本冲突
The problem is that both dependencies depend on a different com.google.guava:guava artifact.
In order to solve the error, you should explicitly depend on a single com.google.guava:guava artifact. So go ahead and add the following in your build.gradle:
compile ‘com.google.guava:guava:27.0.1-jre‘
将以下依赖项复制并粘贴到pom.xml中，然后进行Maven构建：
