‘chromedriver' executable needs to be in PATH

使用selenium的chrome driver总是error .

check setting

1. path 

2.chromedriver.exe location also in the same foldefr as chrome.

But error still exists . 暂时直接指定路径（windows)： browser = webdriver.Chrome("C:\Program Files (x86)\Google\Chrome\Application\chromedriver.exe")

后续继续研究为什么。
