selenium.common.exceptions.WebDriverException: Message: ‘chromedriver’ executable needs to be in PAT

在pycharm中运行程序：

from selenium import webdriver
driver = webdriver.Chrome()
driver.get("http://www.baidu.com")

出现问题下面问题：
selenium.common.exceptions.WebDriverException: Message: ‘chromedriver’ executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

将chromedriver.exe放入这个目录成功解决！
要把chromedriver放到python安装路径下就可以了，不要放到chrome安装目录下，没有起作用
