Chrome升级后，更换chromedriver出现权限问题

如下，想问一下怎么解决……系统是Win10

 driver = webdriver.Chrome()
Traceback (most recent call last):

  File "<ipython-input-2-ec48251f04f8>", line 1, in <module>
    driver = webdriver.Chrome()

  File "D:\Anaconda3\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 73, in __init__
    self.service.start()

  File "D:\Anaconda3\lib\site-packages\selenium\webdriver\common\service.py", line 88, in start
    os.path.basename(self.path), self.start_error_message)

WebDriverException: 'chromedriver' executable may have wrong permissions. Please see https://sites.google.com/a/chromium.org/chromedriver/home

找到问题所在了，googel升级到7.4，对应的chromedriver应该是2.46,我下载成7.4那个了
