Python脚本报错：selenium.common.exceptions.WebDriverException: Message: Service chromedriver.exe unexpect

运行脚本时发现错误如下：

Traceback (most recent call last):
  File "D:\jd233.py", line 6, in 
    driver = webdriver.Chrome("23333")
  File "D:\Python\Python36-32\lib\site-packages\selenium-3.4.3-py3.6.egg\selenium\webdriver\chrome\webdriver.py", line 62, in __init__
    self.service.start()
  File "D:\Python\Python36-32\lib\site-packages\selenium-3.4.3-py3.6.egg\selenium\webdriver\common\service.py", line 96, in start
    self.assert_process_still_running()
  File "D:\Python\Python36-32\lib\site-packages\selenium-3.4.3-py3.6.egg\selenium\webdriver\common\service.py", line 109, in assert_process_still_running
    % (self.path, return_code)
selenium.common.exceptions.WebDriverException: Message: Service chromedriver.exe unexpectedly exited. Status code was: 1

后来发现是这句话有问题：

driver = webdriver.Chrome("chromedriver.exe")

加载chromedriver的时候，必须指明路径，类似下面

driver = webdriver.Chrome("D:\Python\chromedriver_win32\chromedriver.exe")

或者配环境变量

chromedriver 下载地址：

http://chromedriver.storage.googleapis.com/index.html?path=2.30/

修改之后问题解决。
