selenium报错‘unknown error:cannot find Chrome binary’

1、‘unknown error:cannot find Chrome binary’：由于Chrome安装不是默认路径（直接拷贝安装文件），导致selenium找不到安装程序。

解决办法：①Chrome安装到默认路径。②setBinary方法设置程序路径。

2、报错‘The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see https://github.com/SeleniumHe/selenium/wiki/ChromeDriver.The latest version can be downloaded from http://chromedriver.storage.googleapis.com/index.html’

解决办法：找不到ChromeDriver，  setProperty方法设置。
